Abstract
Binary Pt/Pd nanoparticles were synthesized by localized overgrowth of Pd on cubic Pt seeds for the investigation of electrocatalytic formic acid oxidation. The binary particles exhibited much less self-poisoning and a lower activation energy relative to Pt nanocubes, consistent with the single crystal study.
摘要
通过在立方铂晶种上局部生长钯来合成二元铂/钯纳米颗粒，用于研究电催化甲酸氧化。与铂纳米立方体相比，二元颗粒表现出更少的自中毒现象和更低的活化能，这与单晶研究结果一致。
