摘　　要：过渡金属碳化物具有类似于贵金属铂的电子结构,在催化领域有着潜在的应用价值。多酸作为1类尺寸和结构均一的金属氧簇,是制备纳米过渡金属碳化物的理想前驱体。总结了近年来以多酸为前驱体制备碳化钼、碳化钨及碳化钒纳米催化剂的研究进展,为今后这一领域的研究提供借鉴。Transition metal carbides have great potential in catalysis due to their electric structure which is similar to that of Pt.Polyoxometalates are metal-oxygen clusters with homogeneous size and structure,and they are ideal precursors for the preparation of transition metal carbide nanoparticles.This paper summarizes the recent progress in the synthesis of molybdenum carbide,tungsten carbide and vanadium carbide from polyoxometalate-based precursors and provides guidance for the future studies in this field.
