Research progress on preparation of carboxylic acids from heterogeneous catalytic oxidation of primary alcohols
The catalytic oxidation of primary alcohols to carboxylic acids is an extremely important transformation process in organic synthesis,with a wide range of application scenarios.For heterogeneous catalytic oxidation systems,the preparation of efficient catalysts has always been a hot and difficult research topic.Here,a comprehensive review of recent literature on the preparation of carboxylic acids through heterogeneous catalytic oxidation of primary alcohols was presented.The development status and trends of heterogeneous catalysts for the oxidation of primary alcohols were systematically reviewed in terms of single metals and their oxides as well as bimetals and their oxides with or without support.The research progress on heteropoly acid catalysis and green catalysis was then introduced.Finally,the prospects and challenges of heterogeneous catalysis in industrial applications were discussed.
