Abstract

We study the photocatalytic activity of nanocomposites based on θ-phase alumina (Al2O3) with different TiO2 concentrations for heterogeneous photocatalysis and biodestruction of pathogenic microorganisms under action of LED radiation with a wavelength of 405 nm. It is found that all studied nanocomposites have photocatalytic activity. The maximum antibacterial activity (a decrease in the CFU of Staphylococcus aureus 209 P to 86%) is observed for composites with a TiO2 concentration of 8 wt %, which allows us to recommend this nanomaterial as a promising antimicrobial coating.

LED辐射(405 nm)下TiO2-Al2O3纳米复合材料对葡萄球菌的光催化抑菌活性研究
研究了在波长为405 nm的LED辐射下,以不同TiO2浓度的θ相氧化铝(Al2O3)为基材的纳米复合材料对致病菌的非均相光催化和生物杀灭的光催化活性。结果表明,所研究的纳米复合材料均具有光催化活性。当TiO2浓度为8 wt %时,复合材料的抗菌活性最高(金黄色葡萄球菌209p的CFU降低至86%),这使我们能够推荐这种纳米材料作为一种有前途的抗菌涂层。
