The quest for maximum photocatalysis necessitates the unification of hot spots and catalytic sites on photocatalysts. Herein, boron atoms were successfully incorporated into tri-s-triazine unit C3N4 (PCN-B-X), in form isolated B-N coordination. In-situ experimental simulation analyses collectively demonstrated that resulting atomic B centers cyano groups functioned as to amplify charge dynamics localized density. Concurrently, coordination served sites, reducing activation energy oxygen evolution reaction. Whereas, excessive precursor led partial B-B bonding, adversely affecting optical absorption separation. Consequently, optimal photocatalytic activity was achieved at an rate 248.9 µmol h−1 g−1 (λ > 420 nm), when harmoniously aligned PCN-B-20, surpassing by 5.2 times. This study provides insights mechanism suggests approaches develop robust metal-free photocatalysts solar fuel production.

A Robust Pyro-phototronic Route to Markedly Enhanced Photocatalytic Disinfection

Nano Letters, Год журнала: 2024, Номер unknown

Опубликована: Апрель 12, 2024

Photocatalysis offers a direct, yet robust, approach to eradicate pathogenic bacteria. However, the practical implementation of photocatalytic disinfection faces significant challenge due low-efficiency photogenerated carrier separation and transfer. Here, we present an effective improve performance by exploiting pyro-phototronic effect through synergistic combination pyroelectric properties processes. A set comprehensive studies reveals that temperature fluctuation-induced field promotes photoexcited transfer thus facilitates generation reactive oxygen species ultimately enhances performance. It is worth highlighting constructed film demonstrated exceptional antibacterial efficiency exceeding 95% against bacteria under fluctuations light irradiation. Moreover, versatile modulation role in boosting was corroborated. This work paves way for improving harnessing potential various inherent material properties.
