Photocatalytic Asymmetric C‐C Coupling for CO2 Reduction on Cu‐Zn Bimetallic Catalysts with Dipole‐Limiting Effects

Advanced Science, EarlyView.
Asymmetric Cu–Zn dual sites on EDTA‐grafted Ti‐MOF amplify the dipole‐limiting domain field (DLDF), facilitating C–C coupling. This strategy yields an exceptional C2H4 production rate of 308.72 µmol g−1 h−1 with 98.4% electron selectivity in photocatalytic CO2 reduction, highlighting the potential of asymmetric site engineering and local field ...

Intramolecular Synergy of CO2 Activation and H Spillover on Heteronuclear Dual‐Metal Phthalocyanine Assemblies for Selective CO2 Photoreduction

Advanced Science, EarlyView.
The CuNiPc/BiVO4 heterojunction is designed and synthesized for selective CO2 photoreduction. The cascade interfacial Z‐scheme charge transfer and the intramolecular synergy of Cu–Ni dual sites on CO2 activation and H spillover contribute to the high photocatalytic performance and selectivity. ABSTRACT Solar‐driven CO2 conversion holds great promise in

Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

Advanced Science, EarlyView.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.
