“…The morphology of the composite h-TiO 2 /SiO 2 was captured by field-emission scanning electron microscopy (SEM, Zeiss Sigma 300) at an accelerating voltage of 10 kV, and the samples were sputter-coated with a gold film before observation. The surface morphology of the photocatalysts during synthesis, including the carbon sphere templates and h-TiO 2 , was observed by transmission electron microscopy (TEM, FEI Talos F200X G2). − Functional groups in the samples were studied using a Fourier infrared spectrometer, and data were recorded in the range of 4000–400 cm –1 . Photoluminescence spectra were analyzed using an Edinburgh FLS 1000 fluorescence spectrophotometer.…”

Water pollution is a serious problem in both developed and developing countries. Several methods have been used to purify wastewater, among which photocatalytic decomposition is widely used to purify organic pollutants in wastewater. In this work, hollow nanospheres of titanium dioxide TiO 2 were first prepared by the carbon sphere template method and sol−gel method, and then, the hollow nanospheres of titanium dioxide (TiO 2 ) were compounded with silicon dioxide (SiO 2 ) by the impregnation method to generate complexes with different ratios of hollow nanoparticles of titanium dioxide and silicon dioxide. The best degradation performance of the h-TiO 2 / SiO 2 photocatalytic materials was achieved when the ratio of h-TiO 2 to SiO 2 used was 5:1. The cyclic decomposition efficiency of the 5:1 h-TiO 2 /SiO 2 composites showed only a slight change in the photocatalytic capacity compared to the first cycle, thus ensuring the durability of the samples. However, quenching experiments yielded that hydroxyl radicals play a major role in the degradation process, and possible reaction mechanisms are discussed in detail. The high photocatalytic performance of the environmentally friendly h-TiO 2 /SiO 2 nanosphere photocatalysts makes them ideal for water purification applications and offers potential applications for the utilization of solar energy to effectively reduce environmental pollution. The h-TiO 2 /SiO 2 nanophotocatalysts can not only degrade dyes but can also be valuable for self-cleaning glass applications.
