Abstract

The synthesis of a catalyst having all the required physicochemical properties for efficient reactivity is still lacking in the field of heterogeneous catalysis, whereas, the combined roles of these properties are essential for catalyst reactivity. Herein, the efficiency of inverse micelles as nanoreactors in designing mesoporous ceria-zirconia catalysts is reported. The intrinsic properties of the Ce_xZr_1-xO₂ as evidenced by the analyses depend on Zr composition. The superior performance of Ce_0.8Zr_0.2O₂ in benzyl alcohol oxidation with TBHP, under the optimized parameters revealed the structure-induced reactivity, which is strongly ascribed to the combined effects of the modified mesostructure, reducibility and basicity.
