Recent Advances in Noncontact External-Field-Assisted Photocatalysis: From Fundamentals to Applications

ACS Catalysis, Journal Year: 2021, Volume and Issue: 11(8), P. 4739 - 4769

Published: April 5, 2021

The effective separation of photogenerated carriers plays a vital role in photocatalytic reactions. In addition to the intrinsic driving force photocatalysis, an external field generating enhancement effect can provide extra energy system, acting as additional impetus separate charges and thus improving overall catalytic efficiency. Under favorable noncontact conditions, exploring field, different from pure photocatalysis or photoelectrocatalysis, could widen applications technology. this review, four typical fields (i.e., thermal, magnetic, microwave, ultrasonic fields) their coupling effects on are summarized. Specifically, review focuses mechanism characteristics each field's synergistic performance system. charge forces provided by traditional one distinguished defined for first time. challenges future prospects external-field-driven discussed. We hope that will reference research development external-field-assisted give insights in-depth study external-field-coupling-enhanced toward improvement
