abstract = {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 H2 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.}
