Construction of Full-Spectrum-Response Bi₃O₄Br:Er³⁺@Bi₂O_{3- x} S-Scheme Heterojunction With [Bi─O] Tetrahedral Sharing by Integrated Upconversion and Photothermal Effect Toward Optimized Photocatalytic Performance.

ABSTRACT: Designing and optimizing photocatalysts to maximize the use of sunlight and achieve fast charge transport remains a goal of photocatalysis technology. Herein, a full-spectrum-response Bi₃O₄Br:Er³⁺@Bi₂O_{3- x} core-shell S-scheme heterojunction is designed with [Bi─O] tetrahedral sharing using upconversion (UC) functionality, photothermal effects, and interfacial engineering. The UC function of Er³⁺ and plasmon resonance effect of Bi₂O_{3- x} greatly improves the utilization of sunlight. The equivalent layer structure of Bi₃O₄Br and Bi₂O_{3- x} facilitates the construction of high-quality S-scheme heterojunction interfaces with close ato
