Photocatalytic Composite Based on Aluminum Silicate Wool
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.
