Synthesis And Characterization Of Nanocomposite Sno2/Zno And Sno2/Al2O3 And Its Biomedical Application

Abstract

Two nanocomposites were produced by the sol-gel method: ZnO/ SnO₂ and SnO₂/Al₂O₃. Both nanocomposites' optical and structural characteristics are described in detail in the study. In this study, two semiconductors (ZnO- SnO₂₎ and one insulator-semiconductor (SnO₂/Al₂O₃₎ are examined. The Miller indices of the ZnO- SnO₂ and SnO₂/Al₂O₃ nanocomposites were used to determine their particle sizes through powder XRD analysis. Using photoluminescence, optical properties were investigated. It was used to calculate the absorbance band and band gap energy of nanocomposites. Model pollutants such as methylene blue were used to assess the photocatalytic activity of ZnO- SnO₂ and SnO₂/Al₂O₃ photocatalysts under UV light. There are many uses for nanocomposites in the biomedical industry. Both NCs' antimicrobial activity was investigated.
