摘要

要合理设计改良型电催化剂，就必须深入了解反应过程中催化剂的活性位点。然而，分子转化发生在几纳米尺度上，同时进行纳米级化学、电子和结构研究的操作工具非常稀缺。现在，我们利用电化学尖端增强拉曼光谱揭示了 MoS2 上氢进化反应过程中单个活性位点的几何和电子生成与演化。

Monitoring catalytic nanosites in action

Rational design of improved electrocatalysts requires a profound understanding of the catalyst’s active sites during the reaction. However, molecule conversion occurs on the few-nanometre scale and operando tools for simultaneous nanoscale chemical, electronic and structural investigation are scarce. Now, the geometric and electronic creation and evolution of individual active sites during the hydrogen evolution reaction on MoS2 has been unravelled using electrochemical tip-enhanced Raman spectroscopy.
