Science China Chemistry2020年第7期[Cover Story] Prof. Shuangyin Wang et. al. increased the concentration of interfacial sites with rich defects in a 3D hierarchical nanostructured NiO-Co₃O₄ electrocatalyst and investigated its catalytic performances for HMF electro-oxidation. The interface effect created abundant cation vacancies, modulated the electronic properties of Co and Ni atoms, and raised the oxidation state of Ni species. The NiO-Co₃O₄ catalysts show superb HMF oxidation activities with a low onset potential of 1.28 V_RHE. The current study offers an efficient way to create cation vacancies and proves their decisive role in catalyzing the HMF electro-oxidation. (Page 980-986)
