Coupling a semiconductor with exposed high-activity crystal facets and a suitable co-catalyst to form a heterojunction is considered to be a feasible measure to improve photocatalytic activity. Therefore, the novel BiOBr/(001)-TiO2/Ti3C2Tx (BTT-y) were synthesized by in-situ construction. The BTT-y possess a remarkable Rhodamine B (RhB) degradation performance due to there is a better synergy among the three substances. The improvement of RhB degradation performance is mainly attributed to the perfect matching of BiOBr and (001)-TiO2 band structure positions, which is conductive to the formation of heterojunction and thus could expand visible-light absorption range and inhibit the recombination of photo-generated carriers. Furthermore, Ti3C2Tx in the heterojunction would further separate the photo-generated carriers. This study provided reference insights for improving photocatalytic performance with 2D/2D/2D structure. (C) 2021 Elsevier B.V. All rights reserved.
