Advances in aerobic oxidation of alcohols catalyzed by polyoxometalates

多金属氧酸盐作为一类廉价易得的绿色催化剂,在研究开发醇类分子氧氧化新型催化剂体系过程中起着重要的作用。概述了近十几年来多金属氧酸盐对醇类分子氧氧化的催化作用,催化剂体系主要有磷钒钼基类、磷钨酸类等,并介绍了多金属氧酸盐结合超临界二氧化碳体系的研究现状。指出利用多金属氧酸盐结合超临界二氧化碳有可能开发出完全清洁的醇类氧化技术。

As a kind of green inexpensive catalyst, polyoxometalates have played an important role in the research to find new catalyst systems for aerobic oxidation of alcohols. The catalytic effects of polyoxometalates based on phosphovanadomolybdates, phosphotungstates and other types for aerobic oxidation of alcohols during the past two decades are described. The polyoxometalate catalytic activity in supercritical carbon dioxide is also introduced. It is pointed out that the ultimate cleaner aerobic oxidation technology for alcohols may be developed with polyoxometalates in supercritieal carbon dioxide.
