“…To date, titanium dioxide (TiO 2 ), one of the most studied photocatalysts, is often widely used in wastewater treatment and other environmental remediation because of its high efficiency, nontoxicity, good recycling, and low cost. − The final products obtained from photocatalytic oxidation throughout the advanced oxidation process are H 2 O, CO 2 , inorganic ions, and minerals, which usually have a low impact on the environment. − The photocatalytic mechanism of TiO 2 can be understood as follows: under the illumination of light at a specific wavelength, the catalyst generates electron–hole pairs in its conduction and valence bands. The H 2 O and O 2 attached to the catalyst surface will interact with the photogenerated electrons to generate OH – and O 2– radicals, and these generated radicals will then carry out degradation reactions on organic pollutants. , However, due to the TiO 2 band gap of 3.2 eV (anatase crystal type) or 3.0 eV (rutile crystal type), this happens to be activated only under UV radiation (wavelengths less than 387 nm) .…”

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.

With the swift progress of the electronics industry, discarded circuit boards have become an important source of non-degradable waste. In this work, discarded epoxy resin was collected as a precursor to prepare activated carbon (AC) through stepwise carbonization/activation methods. The rough carbon materials with a certain graphite and amorphous structure reveal the multiple oxygen-containing groups on their surface. In the process of studying the adsorption of methyl orange by activated carbon, it is found that the adsorption is in accordance with the quasi-secondary kinetic model, and equilibrium adsorption amounts can reach 41.051 mg/g. The adsorption isotherm of AC is more in line with the Langmuir model, and the saturation adsorption amount at three different temperatures is 23.137 mg/g, 30.358 mg/g, and 37.202 mg/g, respectively. The enthalpy (ΔH) is 17.30 KJ/mol in the adsorption process, which indicates that is a physical process with heat-absorbing capabilities. This work is of great significance with regard to the recycling of waste to reduce pollution and in terms of gaining economic benefits.
