A series of supported Cu2O catalysts on Mg(OH)(2) or gamma-Al2O3 were prepared by coprecipitation-chemical reduction combined with impregnation using Cu(NO3)(2) as precursor salt and hydrazine hydrate as the reducing agent. The crystal phase characteristics and specific suface area of the samples have been characterized by means of X-ray powder diffraction (XRD) and BET method. Catalytic dehydrogenation reaction activity of cyclohexanol over the catalysts was investigated. Results showed Cu2O is the main active component over the supported catalysts. Cu2O Grain has good dispersion in nanoscale. Acid or alkali type of the support has great influence on cyclohexanol dehydrogenation activity of supported Cu2O catalysts. There have cyclohaxene and cyclohexanone products over the supported catalysts. The reaction activity of Cu2O/Mg(OH)(2) catalysts changed with hydrazine hydrate volume. Cyclohexanol conversion and cyclohexanone selectivity can reach to 97.2% and 71.2%.
