稀土镨单原子促进石墨相氮化碳管面内电荷转移以提升纯水中过氧化氢的产率
Rare earth praseodymium single atoms on g-C3N4 tubes for enhanced in-plane charge transfer towards H2O2 production in pure water
摘要
Abstract
Hydrogen peroxide(H2O2)is regarded as an ecologically sustainable oxidant with broad applications.Photocatalytic generation of H2O2 from pure water and oxygen offers a green and energy-efficient alternative to conventional processes.Here,single-atom praseodymium(Pr)was anchored onto tubular porous graphitic carbon nitride(Pr-TCN)via a simple impregnation method for visible-light-induced H2O2 production(λ≥420 nm).The isolated Pr sites accelerate the in-plane charge transfer by establishing a smooth and flexible transfer pathway for photogenerated electrons,and promote *OOH intermediate formation,thereby enhancing water oxidation.The optimized 5％Pr-TCN achieves a H2O2 generation rate of 227.37 μmol g-1 h-1,1.8 times higher than unadulterated TCN.This work demonstrates a scalable single-atom engineering strategy for developing efficient photocatalysts for sustainable H2O2 production.关键词
