Progress in polyoxometalate catalysis

Polyoxometalates (POMs) is a kind of metal-oxygen clusters with well-defined structures, controllable composition, and excellent properties including acidity, redox properties, etc . In recent years, POMs have shown potential application in the field of catalysis, materials, energy conversion and pharmaceuticals and become a hot interdisciplinary research area. This review focuses on the recent progress in the structure design of POMs and their catalytic properties, mainly including POM structure chemistry, acid-base catalysis, redox catalysis, photocatalysis, the catalytic conversion of CO2 and toxic molecules. In addition, the future development of POMs-based catalysis is prospected.
