摘要/Abstract

摘要：

以聚二烯丙基二甲基胺盐酸盐（PDDA）为连接剂，采用原位自组装方式将MoO₃和WO₃负载到碳纳米管（CNTs）上，然后通过乙二醇还原法负载Pt纳米颗粒，得到Pt纳米颗粒均匀分布的Pt/MoO₃-WO₃/CNTs催化剂. 当氧化物总量控制在10 wt%，MoO₃与WO₃摩尔比为1：0.5时，Pt/MoO₃-WO₃/CNTs催化剂催化甲醇氧化活性最高，甲醇氧化峰电流If 高达835 A/gPt. WO₃和MoO₃的加入提高了催化剂的甲醇氧化活性、抗CO中毒能力和稳定性，使得Pt/MoO₃-WO₃/CNTs催化剂表现出优异的甲醇电催化氧化性能.

Abstract:

A composite Pt-based catalyst was prepared by loading MoO₃ and WO₃ nanoparticles onto carbon nanotubes (Pt/MoO₃-WO₃/CNTs). There was a uniform nanoparticle distribution with small particle sizes. This was achieved through an in situ self-assembly method using poly(diallyldimethylammo- nium chloride) as a linker and through subsequent immobilization of the Pt using ethylene glycol as a reducing agent. The total amount of oxide in the CNTs was 10 wt%, and when the molar ratio of MoO₃ to WO₃ was 1:0.5, Pt/MoO₃-WO₃/CNTs showed the highest activity for the electrocatalytic oxidation of methanol with forward peak current of 835 A/gPt. Because MoO₃ and WO₃ improve the electrocatalytic activity for methanol, CO oxidation ability, and the durability of the catalyst, the Pt/MoO₃-WO₃/CNTs catalyst exhibited excellent performance for the electrocatalytic oxidation of methanol.
