Semiconductor photocatalysis holds prodigious promise to drive vital chemical reactions utilizing sunlight. Amongst semiconductors, developing TiO2-related materials is one of the most viable pathways for enhanced photocatalytic performances because of...
AbstractAdvances in LED and photoreactor technology have brought semiconductor photocatalysis to the verge of feasibility of industrial application for the synthesis of value-added chemicals. However, the often observed efficiency losses under intensified illumination conditions still present a great challenge. This perspective discusses the origin of these efficiency losses and what needs to be done to prevent or counteract it and pave the way for efficient, intensified heterogeneous photocatalytic processes. The role of surface catalysis is particularly highlighted as one of the rate-limiting steps.
Graphic Abstract
A hydroxyl radical-mediated aerobic cleavage of alkenes and further sequence esterification reaction for the preparation of carbonyl compounds has been developed by using tubular carbon nitride (TCN) as a general...
We report the synthesis of 1,4-dicarbonyl compounds and substituted alkenes (Mizoroki–Heck type coupling) starting from secondary and tertiary alkyl halides and vinyl acetate or styrene derivatives using visible-light photocatalysis.
This review summarizes recent progress made in the local-field-coupled photocatalytic systems, including electric, thermal, magnetic, and ultrasonic fields, as well as multifield coupling.
