摘要: 由于副产物CO可降低纯Pt催化剂的活性，因此双金属Pt基催化剂已经广泛用于提高直接甲醇燃料电池的性能.本文合成了Pt-Pb六边形纳米板，作为模型催化剂用于甲醇氧化反应（MOR），并通过乙酸（HAc）处理进一步控制纳米板表面Pt和Pb的分布，从而得到Pt-Pb合金表面均相分布的Pt-Pb纳米板以及非均匀分布的HAc处理的Pt-Pb纳米板.结果表明，与HAc处理的Pt-Pb纳米板相比，Pt-Pb纳米板的MOR催化活性和稳定性提高，这主要是由于亲氧性Pb的加入提高了CO容忍度并修饰了Pt的电子结构.

Abstract: Bimetallic Pt-based catalysts have been extensively investigated to enhance the performance of direct methanol fuel cells (DMFCs) because CO, a by-product, reduces the activity of the pure Pt catalysts. Herein, we synthesized Pt-Pb hexagonal nanoplates as a model catalyst for the methanol oxidation reaction (MOR) and further controlled the Pt and Pb distributions on the surface of the nanoplates through acetic acid (HAc) treatment. As a result, we obtained Pt-Pb nanoplates and HAc-treated Pt-Pb nanoplates with homogeneous and heterogeneous distributions of the Pt-Pb alloy surfaces, respectively. We showed that the MOR activity and stability of the Pt-Pb nanoplates improved compared to those of the HAc-treated Pt-Pb nanoplates, mainly due to the enhanced CO tolerance and the modified electronic structure of Pt under the influence of the oxophilic Pb.
