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‐

Nonequilibrium Laser Regulation of the Electronic Structure of the Ni‐Based Electrode for Boosting Nucleophilic Electrooxidation of Alcohols

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports an efficient, simple, low‐cost, and scalable method for overall electrode preparation. Nonequilibrium laser synthesis rapidly yields NiO nanocrystals on which a nickel oxyhydroxide (NiOOH) overlayer is grown in situ. By varying the number of laser pulses, the Ni3+/Ni2+ ratio is precisely tuned, thereby modulating the electronic ...

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...
