摘要 采用CeO2对碳纳米管(CNTs)进行改性,然后利用乙二醇还原法制备了Pt/CeO2-CNTs催化剂,考察了CeO2的掺杂量对催化剂性能的影响。结果表明,所获得的Pt/CeO2-CNTs催化剂极大地促进了甲醇的解离吸附过程,且具有快速电极动力学、高催化电流密度和稳定性,同时其抗CO中毒性能也得到显著提升,为直接甲醇燃料电池阳极Pt基催化剂的工业化奠定了一定的理论基础。

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.
Key words:  cerium oxide    Pt-based catalysts    oxidation of methanol    supports
