摘要：The development of single-atom catalysts with effectiveinterfacesfor biomass conversion is a promising but challenging research area.In this study, a Ru-1/CoO (x) catalystwas successfully fabricated with the impregnation method, which featuredRu single atoms on a cobalt oxide substrate. The Ru-1/CoO (x) catalyst showed superior performance inthe selective electrooxidation of 5-hydroxymethylfurfural (HMF) toproduce 2,5-furandicarboxylic acid (FDCA), a high value-added product.The introduction of Ru single atoms with an ultralow loading of similar to 0.5wt % was revealed to accelerate the electroredox of Co2+/Co3+/Co4+ and improve the intrinsic activityof the CoO (x) substrate with an FDCA selectivityof 76.5%, which is better than that of the pristine CoO (x) electrocatalysts (62.7%). The interfacial synergisticeffect of the Ru-1/CoO (x) interfaceclarified that Ru single atoms can enhance the adsorption of HMF atthe Ru-1/CoO (x) interface, whichpromoted the rate-determining step of the selective C-H bondactivation for FDCA production. This finding provides valuable insightsinto the rational design of single-atom catalysts with functionalinterfaces for biomass upgrading.
