Preparation of Hydrotalcite-Like Catalysts Supported by Mo under Microwave and its Catalytic Properties for Phenol Hydroxylation

Abstract:

Under microwave irradiation, the ternary CuMgAl-HTLcs precursors were synthesized and MoO₄^2- was loaded on the surface of these HTLcs. The results of XRD, FT-IR and SEM analysis indicated that the Mo anion was successfully loaded on the surface of the CuMgAl-HTLcs precursors. The activity of CuMgAl-31 for phenol hydroxylation was the highest, the conversion of phenol was 42.88% and ratio of catechol to hydroquinone was 2:1. CuMgAl-Mo-HTLcs advantageously increased the selectivity of hydroquinone with the ratio of hydroquinone to catechol reaching to 6:1 and about 4% conversion decreasing. Proposed the reaction mechanism of phenol hydroxylation by MoO₄^2- supported HTLcs.
