The cover features unique bimetallic Ni\u2013Rh nanoalloy\/3DOM LaAlO3<\/sub> catalyst synthesized via a well-arrayed polymer crystal templating method and exclusion strategy, demonstrating high efficiency for CO2<\/sub> methanation. Unlike traditional Ni nanoparticle-supported catalysts synthesized by impregnation or other ex situ methods, the direct exclusion of Ni from the 3DOM LaNiAlO3<\/sub> parent material occurs on both the external and internal surfaces of the porous support, resulting in a strong metal\u2013support interaction. The results show that the rich surface-adsorbed oxygen species and basic sites of the catalyst greatly improve its activity toward CO2<\/sub> methanation. https:\/\/pubs.acs.org\/toc\/aamick\/current<\/a><\/p>\n
