Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

Carbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

Hydrogen Migration Enhances Proton‐Coupled Electron Transfer in an S‐Scheme Heterojunction for High‐Efficiency Photocatalysis

Carbon Energy, EarlyView.
Precisely directed built‐in electric field in an S‐scheme heterojunction synergizes photogenerated charge separation with interfacial proton migration, thus co‐localizing electrons and protons on the NOH surface and boosting proton‐coupled electron transfer kinetics in the rate‐determining hydrogen release step. ABSTRACT The kinetic bottleneck in solar‐

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

Chemistry – 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 ...
