Abstract
Dry reforming of methane (DRM) is a promising catalytic process for converting greenhouse gases (CH4 and CO2) into syngas (CO and H2). This study investigates DRM under moderate conditions (550 °C) using supported low‐loading (0.05 wt%) metal (M) catalysts (M = Rh, Ru, Pt, Pd, Ir, Au, and Ni). The reaction was carried out for 6 h with a flow rate of 30 mL/min for both CH4 and CO2, using 0.10 g of catalyst. Among these catalysts, 0.05 wt% Rh/Al2O3 exhibited the highest DRM activity. The effect of catalyst supports revealed that Al2O3 is the most effective support for 0.05 wt% Rh. The DRM activity of Rh species supported on Al2O3 and SiO2 was compared, and the Rh species on Al2O3 outperformed those on SiO2, indicating Al2O3 enhances the DRM activity of Rh. When comparing the DRM activity of Rh nanoparticles and Rh single atoms, it was suggested that Rh nanoparticles might exhibit superior performance for DRM. Coke deposited on 0.05 wt% Rh/Al2O3 is removed by CO2, maintaining stable catalytic activity. These findings provide valuable insights into the design of catalysts that minimize the use of noble metals in DRM reactions.

Abstract
We introduce a novel reaction where electrogenerated acid enhances ethanol upgrading. Electrochemical oxidation of ethanol produces acetaldehyde and protons; the protons act as electrogenerated acid, catalyzing acetalization to form 1,1-diethoxyethane. Stirring the solution shifts the reaction toward acetaldehyde production because electrogenerated acid is neutralized by an electrogenerated base at the cathode.

Catalysts for dehydrogenative conversion of methane (DCM) to higher hydrocarbons are worthy of attention. Indium supported on silica (In/SiO2) was found for effective catalyst for the DCM reaction above 1023 K. Products were ethane, ethylene, acetylene, propylene, benzene, toluene, naphthalene and hydrogen. A highest selectivity of sum of products was 96% at 1098 K and a steady-state sum yield was 2.1% with 63% selectivity at 1173 K. Characterization studies using temperature-programed X-ray diffraction (TP-XRD) and scanning electron microscopy (SEM) indicated that the working state of indium catalyst was liquid metal. Effects of reaction temperature on the product distribution and studies of temperature-programed-reaction (TPR) indicated that liquid-metal indium activated methane and selectively converted to ethane. Higher hydrocarbons were produced from ethane in the gas phase without catalyst.

Electrochemical hydrogenation of toluene (TL) to methylcyclohexane (MCH) with water using a 50 wt% Pt/Ketjenblack (KB) cathode attracts much attention for the hydrogen storage system. We screened non-Pt cathodes and found that lower loading Ru/KB electrocatalyst was effective cathode for the galvanostatic hydrogenation of TL. Even at 1 wt% loading, the Ru/KB cathode was active for the hydrogenation though the working potential was much negative; on the other hand, a 1 wt% Pt/KB cathode was inactive under the same conditions. To improve electrocatalysis of Ru/KB at positive cathode potential, combination of Ru and other metals was studied for the hydrogenation and synergy of Ru and Ir was found. A 5 wt% Ru and 5 wt% Ir supported on KB cathode was as active as the 50 wt% Pt/KB cathode for the hydrogenation. On the basis of experimental facts, a model of reaction mechanism for the electrohydrogenation of TL to MCH applying hydrogen spill-over from Ir to Ru was proposed.

Development of a hydrogen permeable membrane reactor in chemical process has been desired because of a great reduction of energy consumption. Previous studies were limited to Pd membranes. A new type of hydrogen permeable membrane layered three sheets (a reduction-Pt-catalyst sheet broken vertical bar a proton and electron co-conductive sheet broken vertical bar an oxidation-Ptcatalyst sheet) was developed. The middle sheet was prepared by casting a paste of carbon powder and Nafion solution. When a gas mixture of H-2 and He (1: 1) was introduced to the oxidation-catalyst compartment at 298 K, a high concentration of H-2 was observed in the reduction-catalyst compartment, a maximum H-2/He ratio as 217. H-2 selectively permeated through the membrane. This concept was applied for synthesis of H2O2. When O-2 and H-2 were respectively introduced to the Co-N -C reduction-catalyst and the Pt oxidation-catalyst, production of a pure H2O2 aqueous solution of 3.8 mol dm (-3) was succeeded with a good selectivity as 42% based on H2 at 278 K.

Carbon nanotubes (CNTs) are a promising material for superhydrophobic coating. In the present study, we prepared superhydrophobic CNT films by spraying CNT dispersions, and discussed the factors that control superhydrophobicity of the CNT films. Three types of dispersions (i.e., CNTs/ethanol, CNTs functionalized with dodecyl groups/ethanol, and CNTs and trimethylsiloxysilicate (TMSS)/ethanol) were prepared as spraying solutions. As increasing the amount of spray-coated CNTs, hydrophobicity of the resulting films became higher, and eventually superhydrophobicity was observed. The spray-coated CNT films had hierarchical roughness, which is preferable morphology to show superhydrophobicity. The coexistence of TMSS in the film lowered the amount of CNTs required to show superhydrophobicity because TMSS acted like glue that prevented CNTs from aggregating on substrates. Interaction force of CNTs also affected the wettability of the CNT films. The pi-pi interaction of CNTs resulted in the aggregation of them on substrates, which lowered the wettability of the films. From this viewpoint, functionalization of CNTs with dodecyl groups was effective to form superhydrophobic films because the dodecyl groups on CNTs screened the pi-pi interaction of CNTs.

Ni-B/SiC composite films were electrodeposited using conventional Ni electrodeposition baths containing trimethylamine borane and SiC particles. In the present study, we examined the effect of SiC particle size, concentration of SiC particles in electrodeposition baths, thermal treatment, and current density on the properties (i.e., film hardness, SiC content, crystallite structure, and wear resistance) of the electrodeposited Ni-B/SiC composite films. The hardness of the composite films depended on the concentration of SiC particles in the baths; baths containing 1 and 8 g/L of SiC particles provided Ni-B/SiC films with a film hardness of 760 and 858 HV, respectively, which is because the SiC content in the composite films increased with increasing SiC particle concentration in the baths. Current density also affected the hardness of the composite films because both the SiC content and hardness of the Ni-B matrix changed with current density. Thermal treatment at 573 K in air had a significant influence on film hardness; for example, the hardness of Ni-B/SiC composite films was changed from 845 HV to 1499 HV after the thermal treatment. XRD patterns of the composite films revealed that thermal treatment results in a structural change of the Ni-B matrix from an X-ray amorphous structure to a crystalline Ni metal and Ni3B alloy, which leads to hardening of the composite films. Moreover, the Ni-B/SiC composite film showed higher anti-wear performance than Ni/SiC and Ni-P/SiC. (C) 2014 Elsevier B. V. All rights reserved.

Composite blue films of inorganic particles (SiO2, Al2O3 and TiO2) with phthalocyanine (MPc, M = Cu and Pb) were prepared by electrophoresis of protonated MPc using dichloromethane solutions containing trifluoroacetic acid, particles and MPc. The charging of the particles by the adsorption of protonated MPc species from the solution was ascribed to the electrophoresis of these particles. In this way, composite film of MPc with the inorganic particles was formed. SEM images of the composite film reveal a uniform distribution of the particles throughout the composite film, and most of the particles were bonded by fibrous MPc crystallites.

In this study, we investigated composite plating of Ni-SiC by pulse current elelctrolysis using pyridinium (AZPy) and trimethyl ammonium (AZTAB) surfactants with an azobenzene group. The SiC content of Ni/SiC plating using 1μm SiC particles increased with an increase in the pulse frequency from 40vol.% to 60vol.%. This value increased to more than 70vol.% for 0.27μm SiC particles. The roughness of the plating for 1μm SiC particles decreased with an increase in the pulse frequency from 1.7μm to 0.5μm. This value decreased to 0.3μm for 0.27μm SiC particles, which is close to that of the substrate. The hardness of the Ni/SiC plating depended on the SiC content and the highest value obtained was 780Hv. This value was increased to 1340Hv by heat treatment of Ni-P/SiC plating.

Principal investigator - Controlling function of solid catalysts by Atomic Layer Deposition (ALD) technique in the liquid phase

Functional materials were developed using the atomic layer deposition technique in the liquid phase. A solution containing metal precursors was dropped into nanocarbon powders and the solvent was removed, metal precursors are deposited on the nanocarbon surface on a nanoscale. For example, when tetraethyl orthosilicate was used as a precursor, a silica layer of several nanometers was obtained.
We named this liquid-phase atomic layer deposition method the "precursor accumulation method" and developed the synthesis of oxide nanomaterials by this method. We found that LaCoO3 nanoparticles can be synthesized by an extremely simple process and that the obtained LaCoO3 nanoparticles are highly active as an anode catalyst for water electrolysis. The results also suggest that the precursor accumulation method may be applicable to the synthesis of various mixed-metal oxide nanoparticles.

Researches on hydrogen storage medium are active for the purpose of using hydrogen as clean energy. In order to use hydrogen in the infrastructure, a system that generates hydrogen quickly under mild conditions is required. In this study, we developed an electrolysis system that can extract hydrogen from hydrogen storage medium at normal temperature and pressure.
Among several hydrogen storage medium, methanol generated hydrogen at the lowest electrolytic voltage. Analysis of the product showed that methanol electrolysis produced CO2 simultaneously with hydrogen. Therefore, CO2 absorbents were added to the electrolysis system to produce pure hydrogen. Although some CO2 absorbents negatively affected the electrolytic system, it was possible to produce pure hydrogen by using polyethyleneimine without giving negative effect on electrolytic voltage.

Super hard Ni-B/diamond composite coatings were prepared by wet methods. The coating of the first method was composed of electrophoretic deposition of diamond particles with electroless deposition of Ni-B matrix. The Vickers micro-hardness of the coating was 2,500 Hv after heat treatment. The coating of the second method was prepared by electrodeposition of Ni-B/diamond coating from Ni-B bath dispersing diamond particles. The micro-hardness of this coating was 2,300 Hv after heat treatment. The formations of super hard coatings were ascribed to the hardness of diamond and Ni-B matrix.
