In situ construction of Bi₅O₇I/Bi₄Ti₃O₁₂ heterostructure composites with plentiful phase interfaces for the boosted selective oxidation of benzylic alcohols under visible light

Abstract

The novel Z-scheme flower-like Bi5O7I/Bi4Ti3O12 composites were prepared via in-situ grown under hydrothermal-calcination method, which were exhibited outstanding photocatalytic performance for selective oxidation of benzylic alcohols.

Bacitracin-Controlled BiOI/Bi5O7I Nanosheet Assembly and S-Scheme Heterojunction Formation for Enhanced Photocatalytic Performances

“…Generally, a larger number of effective interface contacts is important for the heterojunction system to promote photogenerated charge separation and migration. Compared with the deposition or mechanical-composite methods, a good heterojunction interface contact can be formed by an in situ strategy. − In particular, Bi 5 O 7 I can be obtained by the thermal conversion of BiOI. In this work, when the unique regulatory properties of a biomimetic method were combined, − flower-spherical BiOI/Bi 5 O 7 I (BBOI) heterojunction composites were synthesized by an in situ growth method using bacitracin as a template.…”
