Efficient liquid phase photothermal catalysis realized by Ag 2 O/Bi 4 O 5 I 2 via heat-localization in a microreactor.

By constructing a Ag 2 O/Bi 4 O 5 I 2 p-n heterojunction and applying a heat-localization microreactor, efficient photocatalysis enhanced by both photoinduced carrier separation and the photothermal effect was realized. This work focuses on the utilization of near-infrared light to broaden the absorption spectrum and accelerate the transportation of carriers. Through the production and localization of heat, it provides a novel thought for full-spectrum photocatalysis.
