In-Situ Liquid Phase Transmission Electron Microscopy and Electron Diffraction Provides Mechanistic Insight into Electrochemical CO2 Reduction on Palladium/Palladium Hydride Catalysts

Electrochemical conversion of CO2 (CO2R) offers a sustainable route for producing fuels and chemicals. Pd-based catalysts are effective for selective conversion of CO2 into formate at low overpotentials and CO/H2 at high overpotentials. Furthermore, Pd catalysts undergo morphology and phase structure transformations under reaction conditions that are not well understood. Herein, in-situ liquid phase transmission electron microscopy (LP-TEM) and …
