摘要：

Polymeric graphitic carbon nitride (g-C3N4) supported CuBr2 hybrid material (CuBr2@g-C3N4) was developed by impregnation of CuBr2 on g-C3N4 sheets. The morphology and physiochemical properties were analyzed by powder XRD, SEM, and HRTEM studies. The hybrid CuBr2@g-C3N4 material showed excellent selectivity in the aerobic oxidation of primary/secondary alcohols and benzoins to the corresponding carbonyl compounds in absence of any oxidizing agents. Further, CuBr2@g-C3N4 demonstrated direct oxidation of toluene derivatives to corresponding aldehydes in excellent yields. The g-C3N4 support provides excellent stability and heterogeneity to CuBr2 and was recovered simply by filtration and reused for ten times without appreciable loss in catalytic activity.
