摘要:The present invention provides a rare earth oxide-supported noble metal catalyst which has a high catalytic activity, is greatly improved in the ammonia production activity per weight of the catalyst and per amount of the supported metal, and enables the synthesis of ammonia under mild conditions. The catalyst according to the present invention is characterized in that ruthenium is supported in a layered form on a praseodymium oxide carrier. The catalyst according to the present invention can be produced by burning a praseodymium oxide precursor at a lower temperature, then at a medium temperature and then at a higher temperature to produce praseodymium oxide, then agitating the resultant praseodymium oxide together with a ruthenium supply source in a solvent, then removing the solvent from the mixture, and then burning the resultant product.

摘要:The methanol electro-oxidation catalysts include nano-oxides of rare earth metals (i.e., cesium, praseodymium, neodymium and samarium) and platinum nano-particles. The nano-oxides of the rare earth metals are dispersed during synthesis of a support material, preferably formed from mesoporous carbon. The platinum nano-particles form between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, the rare earth metal forms between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, and carbon and oxygen forming the balance (between about 70 wt % and about 80 wt %) of the methanol electro-oxidation catalyst.

摘要:Manufacture of catalysts containing at least four essential metals: copper, zinc, aluminum and at least one metal selected from the group formed of rare earths and zirconium. The process comprises the formation of a crystallized precipitate of the above-mentioned metals by intimate mixture of a crystallized precipitate of copper, zinc and aluminum, containing less than 0.06% by weight of sodium after washing, with a precipitate of at least one metal of the rare earths group and/or zirconium, containing less than 3% of nitrogen after washing. The catalysts are used in balanced reactions involving alcohols and synthesis gases, and particularly for methanol synthesis.
