Novel Z-Scheme/Type-II ZnO/Bi2MoO6/AgFeO2 Ternary Heterojunctions for Persulfate-Assisted Photocatalytic Elimination of Several Dyes Exposure to Visible Light
Photocatalysis serves as an effective and environmentally friendly approach for the treatment of wastewater and water, with ZnO-based photocatalysts exhibiting significant efficacy in this area. Consequently, we present a novel method that integrates solvothermal, calcination, and hydrothermal processes to produce a ZnO/Bi2MoO6/AgFeO2 ternary photocatalyst, which has shown a remarkable photocatalytic activity in eliminating methyl orange (MO), rhodamine B (RhB), and methylene blue (MB) when exposed to persulfate (SO52⁻) under visible light. The ZnO/Bi2MoO6/AgFeO2 photocatalysts facilitate the activation of SO52⁻ ions, thereby enhancing the degradation of pollutants under visible light exposure. In the presence of the ZnO/Bi2MoO6/AgFeO2 (20%)/SO52⁻ system, MB was entirely decomposed within 75 min, whereas only 39.8% of MB was eliminated using the ZnO/Bi2MoO6/AgFeO2 (20%) sample without SO52⁻. This indicates a synergistic effect between SO52⁻ activation and visible-light photocatalysis in the ZnO/Bi2MoO6/AgFeO2 (20%) system. The enhanced photocatalytic performance of this system is attributed to the activation of SO52⁻ ions by electrons, leading to the generation of sulfate radicals (⦁SO4⁻), improved charge carrier separation, and increased visible light absorption by Bi2MoO6 and AgFeO2. Ultimately, the proposed mechanism for the significantly enhanced photocatalytic activities involves multiple Z-scheme/type II heterojunctions. The findings of this study confirm that the ZnO/Bi2MoO6/AgFeO2 system is a viable visible-light-driven nanocomposite for the purification of water and wastewater.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
