Highly Efficient and Selective Photocatalytic CO2 Reduction to Ethanol by Cu4 Clusters with Adjacent Cu Single Atoms Anchored on Carbon Nitride

Angewandte Chemie, EarlyView.
A catalyst composed of Cu4 clusters and adjacent Cu single atoms anchored on carbon nitride was prepared via a two‐step calcination process. The synergistic effect between Cu4 clusters and Cu single atoms could lower the C─C coupling energy barrier and make it one of the most efficient catalysts for CO2 to ethanol via photocatalysis.

Surface Chemistry of WC Powder Electrocatalysts Probed In Situ with NAP‐XPS

Angewandte Chemie, EarlyView.
Tungsten carbide (WC) is a highly active catalyst for the HER. The reasons for its activity are, however, unclear due to its delicate susceptibility to oxidation and thus passivation. Electrochemical near ambient pressure XPS reveals dissolution of the passive film into the electrolyte under electrochemical working conditions, which effectively enables
