Palladium‐Doping‐Enabled Interface Synergy for Superb Ampere Level Ammonia Electrosynthesis From Nitrate

Angewandte Chemie, EarlyView.
Isolated Pd sites in a metallic Co matrix boost nitrate‐to‐ammonia conversion. Pd doping optimizes intermediate adsorption and reconstructs the interfacial microenvironment, promoting cation enrichment and a hydrogen‐down‐oriented water network. This dual modulation facilitates proton transfer and intermediate stabilization, enabling high ammonia ...

Surface Fermi Level Modulation of Photoanode by Optimized Conducting Nanoparticle Heterointerfaces for Enhanced Photoelectrochemical Water Splitting

Advanced Science, EarlyView.
Optimizing the heterointerface coverage of the conducting Ni2P nanoparticles on the surface of BVO photoanode manipulates the surface Fermi‐level modulation, which significantly enhances photoelectrochemical oxygen evolution reaction. Our multiscale simulations and experimental results reveal that an optimal Ni2P coverage of 9.4% pins the surface Fermi

Dual‐Substrate Synergistic Photocatalysis: Exogenous Reagent‐Free Co‐Removal of Phenol and Cr(VI) via Electron‐Donor‐Mediated Redox Coupling over Modified Carbon Nitride

Advanced Science, EarlyView.
An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐
