Acetone, as a kind of typical volatile organic compounds (VOCs), is mainly discharged into the atmosphere through exhaust emissions, fuel combustion, pharmaceuticals, and printing, etc. It not only causes water pollution but also inhibits the people’s central nervous system, posing a great threat to the ecological environment and human health. Due to its economy and compatibility, the catalytic oxidation method is considered to be one of the effective methods for removing acetone. The development of low-cost and high-efficiency catalysts can bring higher economic benefits. This review covers the research progress of acetone oxidation by noble metal and non-noble metal catalyst systems, and discusses the effects of metal composition, support, preparation method, and morphology on the catalyst activity. Comparison shows that both manganese-based and cobalt-based catalysts are the good substitutes for precious metal platinum-based and palladium-based catalysts, in which the concentration of oxygen vacancies, the number of active oxygen species, and the interaction between substrates are the key factors. In addition, the possible mechanism of catalytic oxidation of acetone is given, and the development of catalytic oxidation of acetone is prospected.

挥发性有机化合物丙酮的催化氧化研究进展

丙酮作为一种典型的挥发性有机化合物(VOC),主要通过废气排放,燃料燃烧,药物和印刷等方式排放到大气中。它不仅造成水质污染,还抑制人的中枢神经系统,对生态环境和人类健康构成巨大威胁。由于其经济性和相容性,催化氧化法被认为是去除丙酮的有效方法之一。低成本和高效催化剂的开发可以带来更高的经济效益。本文综述了贵金属和非贵金属催化剂体系对丙酮氧化的研究进展,并探讨了金属组成,载体,制备方法和形貌对催化剂活性的影响。比较表明,锰基和钴基催化剂都是贵金属铂基和钯基催化剂的良好替代品,其中氧空位的浓度,活性氧种类的数量以及底物之间的相互作用是最重要的。关键因素。此外,给出了丙酮催化氧化的可能机理,并展望了丙酮催化氧化的发展。
