Abstract
In this study, supported of Au2/Zn or Au2Cex/Zn samples were prepared by deposition precipitation method. All samples were characterized by XRD, TEM, ICP and TPR measurements. These catalysts were applied for reforming of methanol reactions, including partial oxidation of methanol (POM), steam reforming of methanol (SRM) and oxidative steam reforming of methanol (OSRM).Au/Zn catalysts were not active for SRM and OSRM reactions, but active for POM reaction. Au2Ce1/Zn supported on ZnO with surface area of 43 m2/g shows the best performance (CMeOH = 86％, SH2 = 88％, SCO2 = 98％) of POM at TR = 150℃.When the amount of methanol is increased by 1.5 times in POM reaction for Au2Ce1/Zn catalyst, the reaction temperature could maintain at 120℃ without an additional heater. Moreover, there is a excellent performance (CMeOH = 90％, SH2 = 91％, SCO2 = 97.3％) of POM reaction at 120℃.
