摘　　要：Nb-containing catalysts have the potential to catalyze carbon dioxide(CO_(2))reduction due to their strong surface acidity and CO_(2)activation sites.Still,they have not been widely used in the development and design of catalysts due to the theoretical/cost/safety limitations.Related advances have been continuously reported in the literature,demonstrating to some extent the promise of catalytic applications of Nb-containing catalysts in this area.In this minireview,we discuss the structure-activity relationships of Nb-containing catalysts for photo-,electro-,and thermocatalytic reduction of CO_(2).The engineering strategies of Nb-containing catalysts for enhancing the conversion and selectivity of CO_(2)reduction are discussed,ranging from Nb doping,noble metal decoration,surface acidity adjustment,oxygen vacancy engineering,and heterojunction construction to Nb or Nb_(2)O_(5) particle decoration.The theoretical calculation research for the possible reaction paths and product selectivity is also discussed.Finally,the prospects for designing and optimizing Nb-containing catalysts are proposed.With a deep understanding of catalytic activity and reaction mechanism,this minireview is expected to present the optimization of the Nb-containing catalysts for efficient and highly selective CO_(2)reduction.
