Methanl dehydrogenation over CU/SiO2 prepared by different method was investigated in a fixed-bed reactor TPR was used to cbaracterize the reduction property of the catalysts.Experimental results showed tha catalysts with differen initial structure exhibited different catalytic behavior in methanol dshydrogenation. With the reaction going on the activity and selecivity of methyl formate and CO decreased and the selectivity of formaldehyde increased due to the sintering and carbon deposition on the surface.
