Abstract

The invention discloses a nickel-rare earth-aluminum oxide catalysis composite film, a preparation method and an application thereof. A layer of nickel-rare earth film with a thickness of 0.05-0.1mu m is plated on the surface of a multi-hole through hole anodic alumina film, finally the nickel-rare earth-aluminum oxide catalysis composite film is obtained, and the mass ratio of the nickel to the rare earth in the formed nickel-rare earth film is 1: (0.001-0.4). The nickel-rare earth-aluminum oxide catalysis composite film is used for the process of hydrogen production from methane steam reforming process, and the catalysis conversion rate of methane is larger than 99.7%.

Description

technical field [0001] The invention relates to a nickel-rare earth-aluminum oxide catalytic composite membrane, a preparation method thereof and an application thereof 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, an...
