W-N-C Tandem Catalytic Centers Mediating EfficientCharge Transfer for the Enhanced Radical-Path U(VI)Photoreduction
W-N-C Tandem Catalytic Centers Mediating EfficientCharge Transfer for the Enhanced Radical-Path U(VI)Photoreduction
研究概述
将缺氧WO3与三维有序大孔氮化碳结合，构筑W—N—C串联中心，增强吸光、界面电荷转移和O2吸附，促进超氧自由基介导U(VI)光还原。优化催化剂16分钟去除率98.6%，容量557.56 mg/g，并降低排氧操作需求。
