Previous research shows that copper based catalysts for steam reforming of methanol (SRM) produce high hydrogen conversion on low temperature and have low CO selectivity. Commonly, catalysts for steam reforming of methanol were synthesized by coprecipitation or impregnation methods. In this research copper based catalyst, which is Cu/ZnO/Al2O3 and Cu/CeO2/Al2O3, were synthesized hydrothermally on a bomb autoclave at high temperature and pressure. X-ray difractogram confirmed the presence of CuO, ZnO, CeO2, and Al2O3 on the synthesized solids. SEM images show that Cu/CeO2/Al2O3 particles are nanosheets with dimension of 40 nm x 350 nm x 1.7 um. Catalytic activity test for steam reforming of methanol reaction on a micro reactor shows 78.10 % conversion for Cu/CeO2/Al2O3 catalyst and 43.60 % for Cu/ZnO/Al2O3 catalyst, each performed at 300 oC, 1 atm. There is no CO detected on the reaction products. <br />
