Abstract: CeO2 is used to modify carbon nanotubes (CNTs),and then Pt/CeO2-CNTs catalysts are prepared with the ethylene glycol reduction method.The effect of CeO2 doping on the performance of catalyst is evaluated.It is shown that the obtained Pt/CeO2-CNTs catalyst greatly promotes the dissociation and adsorption process of methanol,and has fast electrode kinetics,high catalytic current density and stability.Its anti-CO poisoning performance has also been significantly improved.The study lays a certain theoretical foundation for the industrialization of Pt-based catalysts in the anode of direct methanol fuel cells.
