The photocatalytic activity of tin dioxide (SnO2) is limited due to its inadequate response the solar spectrum, wide band gap, and low visible light activity. Here, we synthesized conjugated polyvinyl alcohol (CPVA) modified (CPVA/SnO2) through in-situ hydrothermal synthesis evaluated performance for reduction hexavalent chromium Cr(VI). A series testing characterization results revealed that CPVA was uniformly coated on surface SnO2, forming a mesoporous CPVA/SnO2 heterojunction with enhanced crystallinity reduced oxygen defects, which resulted in an expanded absorption range towards red region. reaction rate constant CPVA/SnO2-A Cr(VI) under (0.060 min-1) 6 times higher than homemade CPVA/TiO2 2.87 SnO2 UV (0.0209 min-1). mechanism indicates exhibited significantly UV-light irradiation by type II heterojunction. When exposed light, photogenerated electrons lowest unoccupied molecular orbital (LUMO) were efficiently transferred heterojunction, reducing electron-hole recombination while also photosensitizing photocatalyst promoting efficient photocatalysis illumination. Ultimately, this process effectively reduces Cr(III). Copyright © 2024 Authors, Published BCREC Publishing Group.
