Revealing Wavelength- and Size-Dependent CO2 Reduction Selectivity via Operando Scanning Photo-Electrochemical Microscopy
Operando photo-SECM demonstrates wavelength-dependent CO2R selectivity on Au/p-GaN photocathodes, with interband excitation favoring CO and intraband favoring H2 due to hot-carrier energy and transport, confirmed by DFT.
