Finding efficient catalyst designs: A high-precision method to reveal active sites

Abstract

Designing efficient electrocatalytic structures requires reliable guidelines. For this purpose, experimental approaches for the characterization of model electrodes in operando conditions are valuable. Reporting in Joule , Agnoli et al. showcase the determination of site-specific reaction onset potentials and Tafel slopes by using electrochemical scanning tunneling microscopy.
