Coupling Strategy for CO₂Valorization Integrated with Organic Synthesis by Heterogeneous Photocatalysis

Angewandte Chemie International Edition, Journal Year: 2021, Volume and Issue: 60(39), P. 21150 - 21172

Published: April 28, 2021

Photocatalytic reduction of CO2 to solar fuels and/or fine chemicals is a promising way increase the energy supply and reduce greenhouse gas emissions. However, conventional reaction system for photoreduction with pure H2 O or sacrificial agents usually suffers from low catalytic efficiency, poor stability, cost-ineffective atom economy. A recent surge developments, in which photocatalytic valorization integrated selective organic synthesis into one system, indicates an efficient modus operandi that enables sufficient utilization photogenerated electrons holes achieve goals sustainable economic social development. In this Review we discuss current advances cooperative photoredox systems integrate organics upgrading based on heterogeneous photocatalysis. The applications virtues strategy underlying mechanisms are discussed. ongoing challenges prospects area critically

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

Sustained CO2-photoreduction activity and high selectivity over Mn, C-codoped ZnO core-triple shell hollow spheres

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Aug. 16, 2021

Abstract Solar conversion of CO 2 into energy-rich products is one the sustainable solutions to lessen global energy shortage and environmental crisis. Pitifully, it still challenging attain reliable affordable conversion. Herein, we demonstrate a facile one-pot approach design core-triple shell Mn, C-codoped ZnO hollow spheres as efficient photocatalysts for reduction. The Mn ions, with switchable valence states, function “ionized cocatalyst” promote adsorption light harvesting system. Besides, they can capture photogenerated electrons from conduction band provide This process continuous due states ions. Benefiting such unique features, prepared demonstrated fairly good performance. work endeavoured shed on role ionized cocatalyst towards production.
