Abstract

It is established that the ZnO–Al₂O₃ oxide coating formed on the surface of aluminosilicate fibers contains hexagonal 13-nm ZnO crystals. The obtained composites demonstrate intense generation of singlet oxygen under the influence of UV radiation. Increasing the radiation power density provided a significant increase (+60%) in the intensity of singlet oxygen generation. It is established that the application of an oxide coating significantly accelerates the processes of adsorption of the aniline blue organic dye from aqueous solutions on the surface of fibers and its photocatalytic decomposition under the influence of near-UV radiation. The kinetics of the dye adsorption process are clearly described by a pseudo-second-order kinetic equation. The application of an oxide coating on the surface of the fibers significantly accelerates the photolysis processes of the dye in the solution. The photolytic decomposition rate of the dye in solution is described by a pseudo-second-order kinetic equation.

基于硅酸铝羊毛的光催化复合材料

结果表明，在铝硅酸盐纤维表面形成的ZnO - al2o3氧化膜含有13 nm的六方ZnO晶体。所得复合材料在紫外辐射的作用下表现出单线态氧的强烈生成。增加辐射功率密度，单线态氧生成强度显著增加（+60%）。结果表明，在近紫外辐射的影响下，氧化膜的应用明显加快了苯胺蓝有机染料在纤维表面的吸附和光催化分解过程。染料吸附过程的动力学用拟二级动力学方程描述得很清楚。在纤维表面涂上一层氧化物可以显著加快染料在溶液中的光解过程。染料在溶液中的光解分解速率用拟二阶动力学方程来描述。
