摘      要：ZnO could be a suitable catalyst for the oxidative conversion of CH4,C2H6 and ***,the main drawback is its thermal ***,ZnO supported on ZrO 2,TiO2,γ-Al2O and SiO2 was investigated for the oxidative dehydrogenation of propane and ethane,and the oxidative coupling of *** stability of the supported ZnO is partially improved,but ZnO reacts with the support material,forming new compounds （Zn-zirconates,-titanates,-aluminates and-silicates）,which already occurs below reaction *** might also be the case for many other heterogeneous catalysts.
