1 Introduction The oxidation of alcohols to their corresponding aldehydes,ketones or carboxylic acids is of significant importance in organic chemistry,and the oxidation products represent important intermediates for the preparation of a various of other compounds[1,2].Catalytic oxidation methods,which employ a variety of metal-containing catalysts,such as Cu (Ⅰ)[3] and so on,developed quickly in recent decades.However,most of the metal containing catalysts are expensive and the reactions generally used the oxidant which may lead to the environmental pollution.
