Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

open access: yesCarbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

open access: yesChemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...
