摘要	CO2 electrochemical reduction (CO2ER) is a promising technology that can convert CO2 into useful chemicals and fuels with simultaneously reducing greenhouse gas emissions. Cu nanoparticles-based catalysts are an optimal choice of CO2ER due to its excellent conductivity and catalytic activity. In this study, we combined scanning transmission X-ray microscopy (STXM) and spectro-ptychography to investigate the chemical and electronic structural changes of the CuAg nanocatalysts before and after CO2ER. We observed that Cu species with the same valence state self-aggregate into separated phases. For the spent CuAg nanocatalysts after CO2ER, most Cu(I) and Cu(0) species are oxidized to Cu(II) together with CuO transforming into undetermined Cu(II) species. We believe these mechanisms are the key reason why the CuAg nanocatalysts lost catalytic activity. Such information will be highly valuable for understanding Cu nanoparticles catalyzed CO2ER. © 2023
