Abstract

For the synthesis of Ag-doped MnO2 nano-wires-like morphology, the hydrothermal method was used. The composite of Ag-doped MnO2 nano-wires nanocomposite with g-C3N4 (Ag–MnO2/g-C3N4 (10 %) was made using an ultra-sonication approach. The formation of doped and un-doped MnO2 nano-wires (NWRs) was confirmed by XRD, and for the detection of functional groups, FTIR analysis was done. Surface morphology and optical analysis were done by SEM and UV–visible spectro-photometry. The Ag–MnO2/g-C3N4 (10 %) showed tremendous photo-catalytic efficiency towards MB and BA. Ag–MnO2/g-C3N4 (10 %) exhibited 51.38 % degradation of BA and 83.67 % of MB under visible light irradiation. Ag-doped MnO2 nano-wires (NWRs) exhibited better photo-catalytic efficiency as compared to bare MnO2. This work represents that the photo-catalyst Ag–MnO2/g-C3N4 (10 %) is capable of photodegradation of dyes and organic compounds as it has a greater potential for establishing a better green environment. © 2024 Korean Physical Society
