Recent Advances in Photocatalytic Urea Synthesis via C−N Coupling From C/N‐Containing Species: A Mini Review

EcoEnergy, EarlyView.
This review systematically compares photocatalytic urea synthesis from various C (CO2, CO, CH3OH) and N (N2, NH3, NO3−) sources. It highlights C–N coupling mechanisms, key challenges, and future directions, offering a framework to guide rational catalyst design for sustainable, solar‐driven urea production.

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...
