The harmful cationic dyes present in industrial waste significantly decrease the effectiveness of remedy operations. Considering the horrendous impact of these dyes on the environment and biodiversity, silver bromide (AgBr) and chitosan (CS) doped copper ferrite (CuFeO) nanostructures (NSs) were prepared by the co-precipitation route. In this work, The surface characteristics of CuFeO can be altered by CS, potentially enhancing its catalytic reaction compatibility. The functional groups in CS interact with the surface of CuFeO, influencing its catalytic behavior. AgBr can have an impact on the dynamics of charge carriers in the composite. Better charge separation and transfer which is essential for catalytic processes. The catalytic degradation of RhB was significantly enhanced (100 %) using 4 wt% of AgBr-doped CS-CuFeO catalysts in a basic medium. The significant inhibitory zones (9.25 to 17.95 mm) inhibitory in maximum doses were seen against Gram-positive bacteria (S. aureus). The bactericidal action of AgBr/CS-doped CuFeO NSs against DNA gyrase and tyrosyl-tRNAsynthetase S. aureus was rationalized using molecular docking studies, which supported their function as inhibitors.
工业废水中存在的有害阳离子染料会显著降低补救操作的效果。考虑到这些染料对环境和生物多样性的可怕影响,通过共沉淀法制备了银溴化物 (AgBr) 和壳聚糖 (CS) 掺杂的铜铁氧体 (CuFeO) 纳米结构 (NSs)。在这项工作中,CS 可以改变 CuFeO 的表面特性,可能会提高其催化反应的兼容性。CS 中的官能团与 CuFeO 的表面相互作用,影响其催化行为。AgBr 可能会影响复合材料中载流子的动力学。这对于催化过程至关重要。在碱性介质中,使用 4wt% 的 AgBr 掺杂 CS-CuFeO 催化剂可显著增强 RhB 的催化降解(100%)。在最大剂量下,对革兰氏阳性菌(金黄色葡萄球菌)观察到显著的抑菌区(9.25 至 17.95 毫米)。AgBr/CS 掺杂 CuFeO NSs 对 DNA 回旋酶和酪氨酸-tRNA 合成酶金黄色葡萄球菌的杀菌作用通过分子对接研究得到了合理化,这支持了它们作为抑制剂的功能。
