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

open access: yesEcoEnergy, 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.
