Abstract: The present invention relates to a method for preparing a catalyst comprising a ruthenium-containing catalyst layer highly dispersed with a uniform thickness on a surface of a substrate having a structure, which comprises first aging a mixed solution of a ruthenium precursor-containing solution and a precipitating agent to form a ruthenium-containing precipitate seeds, secondarily aging the first aged mixed solution to grow the seeds thereby forming ruthenium-containing precipitate particles, and then contacting the particles with a substrate to deposit the particles on the surface of the substrate. Since the catalyst has a structure in which the round shaped ruthenium-containing precipitate particles are piled to form the ruthenium-containing catalyst layer, it has a large specific surface area. Thus, the catalyst may exhibit excellent catalytic performance in various reactions for producing hydrogen using a ruthenium catalyst.

Abstract translation: 本发明涉及一种制备催化剂的方法，所述催化剂包括在具有结构的基材的表面上高度分散均匀的含钌催化剂层，其包括首先老化含钌前体溶液和 沉淀剂形成含钌沉淀物种子，二次老化第一老化混合溶液以种植种子，从而形成含钌沉淀颗粒，然后使颗粒与基材接触以将颗粒沉积在基材的表面上。 由于催化剂具有将圆形含钌沉淀物颗粒堆积以形成含钌催化剂层的结构，所以其比表面积大。 因此，催化剂可以在使用钌催化剂制备氢的各种反应中表现出优异的催化性能。
