“…Acid etching of CoMn spinel significantly increased the active lattice oxygen, thus promoting the elimination of acetone according to the MvK mechanism. Xiao et al fitted the kinetic data of the ethyl acetate oxidation on La modified CuMn spinel and found that the MvK model was consistent with the description of the kinetic behavior of the catalyst. Ethyl acetate was chemically adsorbed on Mn 2 O 3 phase and reacted with active oxygen to form oxidation products, accompanied by the reduction of Mn 2 O 3 to MnO.…”

“…67 However, the addition of excessive Ce reduced the specific surface area and occupied the surface oxygen vacancy causing adverse effect. Xiao et al 68 synthesized La modified CuMn spinel for the degradation of ethyl acetate. The doping of La did not change the crystal structure of the catalyst but significantly improved the specific surface area and lowtemperature reducibility.…”

Volatile organic compounds (VOCs) harm the environment and human health and have been of wide concern and purified efficiently by catalytic oxidation. Spinel oxides, mainly composed of transition metal elements with low price and extensive sources, have been widely investigated as efficient and stable catalysts for VOCs oxidation due to their adjustable element composition, flexible structure, and high thermal/chemical stability. However, it is necessary to dissect the design of the spinel in a targeted way to satisfy the removal of different types of VOCs. This article systematically summarizes the recent advances regarding the application of spinel oxides for VOCs catalytic oxidation. Specifically, the design strategies of spinel oxides were first introduced to clarify their effect on the structure and properties of the catalyst. Then the reaction mechanism and degradation pathway of different kinds of VOCs on the spinel oxides were in detail summarized, and the characteristic requirements of the spinel oxides for various VOCs purification were analyzed. Furthermore, the practice applications were also discussed. Finally, the prospects were proposed to guide the rational design of spinel-based catalysts for VOCs purification and intensify the understanding of reaction mechanisms.
