Electrocatalysis

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.
