| Zusammenfassung: | © 2021 Wiley-VCH GmbH. The electrosynthesis from 5-hydroxymethylfurfural (HMF) is considered a green strategy to achieve biomass-derived high-value chemicals. As the molecular structure of HMF is relatively complicated, understanding the HMF adsorption/catalysis behavior on electrocatalysts is vital for biomass-based electrosynthesis. The electrocatalysis behavior can be modulated by tuning the adsorption energy of the reactive molecules. In this work, the HMF adsorption behavior on spinel oxide, Co3 O4 is discovered. Correspondingly, the adsorption energy of HMF on Co3 O4 is successfully tuned by decorating with single-atom Ir. It is observed that compared with bare Co3 O4 , single-atom-Ir-loaded Co3 O4 (Ir-Co3 O4 ) can enhance adsorption with the CC groups of HMF. The synergetic adsorption can enhance the overall conversion of HMF on electrocatalysts. With the modulated HMF adsorption, the as-designed Ir-Co3 O4 exhibits a record performance (with an onset potential of 1.15 VRHE ) for the electrosynthesis from HMF |
