In this work, novel insights into the influence of different nanocrystal structures on the electrocatalytic oxidation of methanol are reported. Herein, we have successfully prepared high-yield PtPb nanoplates in the diethylene glycol (DEG) solvent. The as-obtained PtPb nanoplates with a large surface area of the (102) facet show higher MOR activity and superior durability in alkaline electrolyte compared with both zero-dimensional PtPb nanoparticles and commercial Pt/C. Further chronoamperometric (CA) measurements and discrete Fourier transform (DFT) calculations indicate that the PtPb nanoplates possess much better operation durability and CO tolerance due to the negative adsorption energy of the (102) facet.

用于高效甲醇电氧化反应的平面PtPb纳米板的形状控制合成。

在这项工作中，报道了有关不同纳米晶体结构对甲醇电催化氧化影响的新颖见解。在这里，我们已经成功地在二甘醇（DEG）溶剂中制备了高产率的PtPb纳米板。与零维PtPb纳米粒子和市售Pt / C相比，具有（102）晶面大表面积的PtPb纳米板具有更高的MOR活性和优异的碱性电解质耐久性。进一步的计时安培（CA）测量和离散傅里叶变换（DFT）计算表明，由于（102）面的负吸附能，PtPb纳米板具有更好的操作耐久性和CO耐受性。
