Uncovering the synthesis of a visible light-driven manganese-doped copper bismuth oxide catalyst for enhanced degradation of dye: Insights into the factors affecting the degradation

In recent times, effluent pollution has had an exceptionally detrimental effect on aquatic life as well as human beings. The management of wastewater has emerged as a formidable undertaking for scientists owing to the existence of organic contaminants. Herein, we synthesized the manganese-doped copper bismuth oxide (Mn0.15Cu0.85Bi2O4) through hydrothermal method and employed them for successfully eliminating complex pollutants. The assessment of the visible light-induced photocatalytic efficacy of the catalyst was performed for the degradation of methyl violet (MV). MV had a degradation of 89.68% when CuBi2O4 was used. However, the degrading rate of the Mn0.15Cu0.85Bi2O4 escalated to 99.18% in 36 min. The rate constant exhibited a rise between 0.0627 and 0.1134 min(-1), confirming the effectiveness of the Mn0.15Cu0.85Bi2O4. The effectiveness of the Mn0.15Cu0.85Bi2O4 is due to its superior surface area (51.97 m(2)/g), which arises from the integration of Mn-ions. Additionally, examining the impact of different reaction variables revealed a substantial correlation with the elimination of MV dye. The potential reason for the deterioration of MV could be attributed to the generation of center dot OH and O-2(center dot-) radicals, which was confirmed by radical trapping experiments. The photostability of the generated Mn(0.15)Cu(0.85)Bi(2)O(4)catalyst exhibited remarkable characteristics. Ultimately, this study presents a technique for creating effective catalysts for treating wastewater that is both economical and practical.
