摘要：
This paper interrogates the catalytic properties of monometallic copper and various bimetallic Ru-Cu, Rh-Cu, Ag-Cu, Ir-Cu catalysts supported on binary oxide ZrO2-Al2O3 or ZnO-Al2O3 in oxy-steam reforming of methanol reaction. X-ray diffraction, specific surface area and porosity, temperature programmed reduction and temperature programmed desorption were used to characterize monometallic and bimetallic copper supported catalysts. The promoting effect of noble metals on reducibility and catalytic properties of copper catalyst was proven. The activity results showed that rhodium doped copper catalysts supported on ZnO-Al2O3 exhibited the highest conversion of methanol and a high selectivity towards main products of the reaction demonstrating its potential application in fuel cell technology.
