Description

technical field [0001] The invention relates to a nickel-aluminum trioxide catalytic composite membrane, its preparation method and its application in hydrogen production by catalytic methane steam reforming. Background technique [0002] The anodic aluminum oxide film has the characteristics of highly ordered pores and large specific surface area, and has broad application prospects in the field of catalytic materials. Catalytic membranes can be prepared on anodized aluminum membranes by dipping and sol-gel methods. [0003] For example: Ganley JC et al impregnated the porous anodized aluminum membrane in RuCl 3 and Ni(NO 3 ) 2 In the mixed solution, Ru-Ni-Al was prepared 2 o 3 The membrane catalyst was used to catalyze the decomposition of amines, and the experiments showed that the conversion of amines increased significantly with the increase of Ru loading. [0004] Gao Yuan et al. used anodic oxidation method to prepare porous alumina film, and then used sol-gel m...
