This present investigation focused on novel p-type bismuth ferrite (BiFeO₃)/n-type tin sulfide (SnS₂) heterostructure photocatalyst has been favorably attained via a facile two-step process followed by co-precipitation approach for enhances the photocatalytic activity through the degradation of Methylene Blue (MB) and Rhodamine B (RhB) organic dyes under visible-light illumination. Structural, optical, and photocatalytic behavior of the prepared BiFeO₃ and BiFeO₃/SnS₂ photocatalysts are carefully explored. The photocatalytic efficiency of BiFeO₃/SnS₂ nanocatalyst was calculated to be 83%, 78% for MB and RhB, respectively, within 120 min illumination whereas the pure BiFeO₃ nanoparticle was 58% and 56% for MB and RhB. This prominent enhancement of visible light photocatalytic activity can be ascribed to the separation as well as the transfer of photogenerated charge carriers, successful exploitation of visible light absorption and donates the enlarged number of photocatalytic active sites by the formation of BiFeO₃/SnS₂ p-n heterojunction.

目前的研究集中在新型 p 型铁酸铋 (BiFeO ₃ )/n 型硫化锡 (SnS ₂ ) 异质结构光催化剂上，通过简单的两步法和共沉淀法顺利实现了光催化活性，通过亚甲基蓝 (MB) 和罗丹明 B (RhB) 有机染料在可见光照射下的降解。仔细研究了所制备的 BiFeO ₃和 BiFeO ₃ /SnS ₂光催化剂的结构、光学和光催化行为。BiFeO ₃ /SnS ₂的光催化效率在 120 分钟的光照下，MB 和 RhB 的纳米催化剂计算结果分别为 83%、78%，而纯 BiFeO ₃纳米颗粒对于 MB 和 RhB 分别为 58% 和 56%。可见光光催化活性的显着增强可归因于光生电荷载流子的分离和转移、可见光吸收的成功利用以及通过形成 BiFeO ₃ /SnS ₂ pn 异质结提供了更多的光催化活性位点.
