Research Progress of Composite Metal Oxide Catalysts for the Oxidation of Glycerol to Acrylic Acid

With the shortage of fossil fuels and the environmental problems caused by their utilization, renewable biomass resources have gradually become an important source for the production of fuel and chemicals. In recent years, as the main by-product of biodiesel production, glycerol has attracted widespread attention. The utilization of glycerol to produce high value-added products and the development of relevant conversion technologies have also become a hot spot for scholars at home and abroad. Among many conversion technologies, the selective oxidation of glycerin to acrylic acid has shown broad development prospects.It has important economic and social significance to study the reaction and especially the catalyst. This article summarizes the current research status of composite metal oxide catalysts for the selective oxidation of glycerol to acrylic acid. The current types of catalytic systems used in the reaction and the understanding of the catalytic reaction mechanism of glycerol oxidation to acrylic acid are briefly introduced. Moreover, the existing problems and future prospects are also analyzed and expected.
