摘要
Abstract Scandium oxide (Sc 2 O 3 ) is considered as omnipotent “Industrial Ajinomoto” and holds promise in catalytic applications. However, rarely little attention have been paid to its electrochemistry. Here, we reported the first nanocasting design of high‐surface area Sc 2 O 3 with abundant oxygen vacancies (mesoporous V O ‐Sc 2 O 3 ) for efficient electrochemical biomass valorization. In the case of the electro‐oxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA), quantitative HMF conversion, high yield and high faradic efficiency of 2,5‐furandicarboxylic acid (FDCA) via the hydroxymethylfurancarboxylic acid (HMFCA) pathway were achieved by this advanced electrocatalyst. The beneficial effect of the V O on the electrocatalytic performance of the mesoporous V O ‐Sc 2 O 3 was revealed by the enhanced adsorption of reactants and the reduced energy barrier in the electrochemical process. The concerted design, in‐situ and ex‐situ experimental studies and theoretical calculations shown in this work should shed light on the rational elaboration of advanced electrocatalysts, and contribute to the establishment of a circular carbon economy since the bio‐plastic monomer and green hydrogen are efficiently synthesized.
