Steering the behavior of photogenerated carriers in semiconductor photocatalysts: a new insight and perspective

Journal of Materials Chemistry A, Год журнала: 2021, Номер 9(42), С. 23765 - 23782

Опубликована: Янв. 1, 2021

The current semiconductor photocatalysts only exhibit unsatisfactory photocatalytic efficiency, due to the easy recombination of photogenerated carriers. Regulating separation and transfer carriers reducing are essential for improving catalytic efficiency photocatalysts. is produced by attraction Coulomb force. Consequently, requires an additional driving force counteract However, exploring mechanism carrier regulation from perspective has received sporadic attention. This review firstly starts fundamental impairment performance. Then it focuses on several main strategies regulating behavior aspect carriers, including heterojunction design，construction intramolecular donor-acceptor (D-A) system, exciton regulation, electron spin regulation. Subsequently, advanced characterization techniques latest developments theoretical calculations migration have been introduced. In end, we summarize challenges put forward prospects future development

Abstract Over the past several decades, much effort has been applied to atmospheric nitrogen oxide (NO x ) abatement. The current techniques require high energy consumption and result in secondary pollution. Particularly, removal of low dose ( < 200 ppm) NO very challenging. Though graphitic carbon nitride (g‐CN), an eco‐friendly sustainable material was tried as a promising metal‐free photocatalyst for Herein, one‐step, efficient calcination approach is developed prepare amorphous (ACN) with N3 C ‐site vacancies. visible‐light responsive range expanded activation barrier NO triple bonds sharply decreased by one order magnitude; 0.19 eV when compared 2.22 g‐CN. These modifications allow efficiency ACN reach 57.1% which among highest visible light. unique vacancies are well maintained after photocatalytic oxidation, shows exceptional structural stability. This boosts generation singlet oxygen 1 O 2 superoxide radical • − complete removal. study sheds light on active site design performance enhancement g‐CN based materials vacancy engineering.
