Abstract
Heterojunction fabrication is a general and practical method for producing high-efficiency photocatalysts. The photocatalyst of S-type heterojunction greatly improves the carrier separation efficiency to a certain extent, thereby promoting the degradation efficiency. In this work, we reported a unique S-scheme heterojunction photocatalyst composed of n-type Cs3Bi2Br9 (CBB) and p-type BiOBr with well-defined junction interfaces for photocatalytic degradation of Rhodamine B (RhB). By soaking CBB in an aqueous alcohol solution, the desirable BiOBr/CBB heterostructure was created in-situ, forming the intimate interfaces and facilitating the separation of photogenerated charge carriers. Compared with the pristine CBB, a substantial enhancement in photocatalytic performance of BiOBr/CBB heterostructure was achieved through an optimized water treatment. The results showed that the degradation efficiency of the optimal BiOBr/CBB heterostructure reached 98.55 % in 20 min.
期刊介绍：
Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications.
Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
