Published: March 21, 2024

Abstract Solar‐to‐chemical energy conversion thorugh photocatalytic technology has garnered significant attention due to its potential for clean hydrogen pro duction, pollutant degradation, and carbon dioxide reduction. However, relatively low solar‐to‐chemical efficiency hinders industrial development. External fields have currently emerged as a supplementary source augment the overall catalytic efficiency. Recently, performance been considerably enhanced through magnetic field modulation, which promotes separation transfer of photoexcited charge carriers. This article systematically reviews recent research progress field–assisted photocatalysis, discussing phenomena such negative magnetoresistance effect, Lorentz force, spin polarization. It comprehensively analyzes effect on critical processes in photocatalysis: light absorption, charge‐carrier separation, surface reactions. In particular, this review focuses spin‐relaxation mechanism, explains how electron lifetime is extended polarization, proposes design strategies spin‐polarized materials. Finally, discusses challenges opportunities enhancing The ultimate objective offer notable theoretical experimental insights that can guide development high‐performance photocatalysts systems.

Unification of hot spots and catalytic sites on isolated boron centers in porous carbon nitride nanosheets for efficient photocatalytic oxygen evolution

Nano Energy, Journal Year: 2023, Volume and Issue: 116, P. 108800 - 108800

Published: Aug. 18, 2023

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.
