Abstract:

Selective oxidation of light olefins to produce the corresponding aldehydes and other oxygen-containing compounds is a key step in the production of important organic chemical intermediates and products. Molybdenum bismuth composite metal oxides have attracted wide attentions in industry and academia because of their excellent catalytic performance. However, there is still debate on the selective oxidation mechanism on the catalyst and the nature of the catalytic reaction. This work systematically reviews the research progress of using molybdenum bismuth composite metal oxides as catalyst in selective oxidation of light olefins to aldehydes. It is pointed out that the micro-structure and catalytic performance of molybdenum bismuth composite metal oxides are mainly controlled by three strategies including the phase structure of bismuth molybdate, additives and carriers. And the selective oxidation reaction mechanism over the molybdenum bismuth composite metal oxides is discussed and summarized. Finally, the development of molybdenum-bismuth composite metal oxides in selective oxidation reaction is prospected to provide ideas for their modification and the exploration of efficient catalysts for light olefins to oxygen-containing compounds.
