摘　　要：柠檬酸法在复氧化物材料制备中占有重要地位,它具有分散均匀、制备温度低、产物粒径小的特点.以特定组成和结构的柠檬酸络合物为前驱体,直接分解可得到纯度较高的复氧化物,从中可以了解复氧化物的形成过程.本文从配位结构化学的角度,评述以钛、钒、钼和钨柠檬酸络合物为前驱体制备复氧化物材料的研究进展.Citrate method is one of the popular processes for the synthesis of mixed oxide.This is due to the advantages of its homogeneous,low decomposed temperature,and resulted small particle sizes.Citrate complexes are considered as the molecular precursors for the mixed oxides by thermal decomposition,which may show different compositions and structures.The mixed oxides can be used as catalysts and the other materials by citrate process.In the present paper,recent progress of Ti,V,Mo and W citrate complexes as precursors for the preparation of mixed oxides is reviewed.
