A series of heterogeneous copper nanocatalysts supported on calcined cow bone synthesized via osmosis and impregnation methods and characterized by different analysis such as FT-IR,UV – Vis, FE - SEM, BET surface area, ICP and etc. The nanocatalytic activity of this nanocatalysts has tested in hydroxylation reaction of phenols by H 2 O 2 and different parameters of this reaction investigated in aqueous media under mild conditions. For analysis of reaction products, high performance liquid chromatography technique and gas chromatography technique is used. Results indicated that the selective oxidation of phenol with H 2 O 2 by a radical substitution mechanism produces three main reaction products: Catechol, Hydroqinone and Resorcinol. The nanocatalysts have the advantage of very cheap supports, and easy nanocatalyst recovery. The effects of Cu atomic ratio, reaction time, temperature, amount of catalyst, and the type support on the conversion of phenols yields were investigated. Under the optimized conditions,20mg catalyst showed a maximum of 93.3% phenol conversion and 92.24% selectivity for hydroquinone. Also we got the 97.96% resorcinol in the harsh condition.
