“…(AB 2 O 4 ) type oxides are considered to be promising catalysts for the catalytic oxidation of VOCs due to the electron tunability of their metal elements, which can effectively improve the redox capacity and oxygen mobility of catalysts. − The modification of spinel catalysts generally revolves around the construction of defects, A and B site element replacement, morphological design, and other methods. − In recent years, it has been found that controlling the dispersion state and crystalline structure of the spinel to modulate the electronic structure of the metal ions can effectively advance the redox cycle and active site status in spinel catalysts, and impact the behavior of the reactants on the surface of the catalyst, so as to control the reaction activity . Enhancing the dispersion of the spinel is a common choice to modulate catalytic activity.…”
