Preparation of VO3-, MoO42- and WO42-Catalysts Supported on Hydrotalcite- Like CuMgAl under Microwave and Their Catalytic Behavior for Phenol Hydroxylation

Abstract

Abstract: VO3-, MoO42-, and WO42--supported CuMgAl catalysts were prepared using the impregnation method under microwave irradiation and were used to catalyze phenol hydroxylation. Compared with the CuMgAl precursors, MoO42?-supported CuMgAl gives a high selectivity for hydroquinone without significant changes in the phenol conversion.

Key words: hydrotalcite-like compound, microwave, supported catalyst, phenol, hydroxylation
