摘　　要：Utilization and storage are the two main themes of green hydrogen.In hydrogen-involved system,development of highly active catalysts to achieve catalytic hydrogenation under mild conditions is a prerequisite for coupling with green hydrogen,so that green hydrogen with low outlet pressure can be directly used as a hydrogen source.To achieve this aim,we developed a high active Co-CoOx@NC catalyst with metal/metal oxide induced by N-doping.The work function and Bader charge calculations reveal that N-doping can induce interfacial electrons rearrangement to form Co-CoOx interface on the surface of Co nanoparticles(NPs).The interface is the dual active sites,where Co plays a role in H_(2) dissociation and CoOx can enhance the adsorption and activation of aldehyde compounds.Different from traditional dissimilar metal/oxide interface,the Co-CoOx interface can effectively shorten hydrogen spillover distance and energy barrier,and thus exhibits high catalytic performance in hydrogenation of a variety of bio-derived aldehydes under aqueous-phase and mild reaction conditions that can couple with green hydrogen.
