摘要

本研究通过扫描电化学电池显微镜，在单粒子水平上定量研究了钯纳米晶体上依赖于面的析氢反应。值得注意的是，与具有{100}面的Pd立方体相比，具有{111}面的Pd八面体表现出显著优于具有{100}面的Pd立方体的内在析氢反应活性。这项工作为探索纳米晶体电催化剂的内在特性提供了一种教学方法，并在单一实体上建立了明确的结构-活性关系。

Shape-controlled hydrogen evolution reaction of single Pd nanocrystals†

This study presents a quantitative investigation of the facet-dependent hydrogen evolution reaction on Pd nanocrystals at the single-particle level, achieved by scanning electrochemical cell microscopy. Notably, Pd octahedra with {111} facets demonstrated significantly superior intrinsic hydrogen evolution reaction activity, as compared to the Pd cubes with {100} facets. This work provides a pedagogical approach for probing the intrinsic activities of nanocrystal electrocatalysts and establishes a definitive structure–activity relationship at the single-entity level.
