degradation of MPs is still only in the laboratory stage at this stage, and problems such as the degradation of MPs in actual water bodies have not been carried out, so how to solve the above problems is the focus of future research in the field of g-C3N4 photocatalytic degradation of ...
Recently, the environmental impacts of microplastics have received extensive attention due to their accumulation in the environment. However, developing efficient technology for the control and purification of microplastics is still a big challenge. Herein, we investigated the photocatalytic degradation of ty...
Photocatalytic degradation refers to an environmentally friendly technology that utilizes semiconductor materials, such as TiO2 and ZnO, to break down organic pollution, such as microplastics, into water, carbon dioxide, and inorganic acids. This process is triggered by the generation of highly reactive...

In the photocatalytic degradation of microplastics, the reactive oxygen species (ROS), including hydroxyl (OH) and superoxide ions (O2-), play an essential role in the process, resulting in the breakdown of the polymeric chain and the generation of reaction intermediates. Therein, the...
Photocatalytic degradation of polyethylene and polystyrene microplastics by α-Fe2O3/g-C3N4MicroplasticsPhotocatalystsα-Fe2O3/g-C3N4Visible lightThis study investigated the photodegradation of microplastics (MPs) by α-Fe2O3/g-C3N4. The effects of α-Fe2O3/g-C3N4 on MPs' surface were ...
The effect of these surfactants on the catalytic properties and the degradation efficiency of the polymeric matrix (CuO/PVA) has been investigated using 1,3,7-Trimethylpurine-2,6-dione (caffeine) as a major pollutant. From the kinetics studies, R2 = 0.9939 for Freundlich isotherm and 0.9839 ...
The optimization could focus on simultaneous development of high-performance catalysts and in the elucidation of fundamentals aspects involved in MP degradation. Multiphysics simulations have been applied to improve various engineering processes, including AOPs [146], showing that it is possible to optimize...
