CdIn 2 S 4 / BiOCl nanophotocatalyst is a new type of composite visible light catalyst, which exhibits excellent photocatalytic degradation activity due to its unique facet heterogeneous structure, and has an important application prospect in the treatment of dye wastewater.

Description

technical field [0001] The invention belongs to the preparation of photocatalytic nanocomposite materials and the application in the field of environmental water pollution control, and relates to a binary 2D / 2D CdIn 2 S 4 Preparation method and application of BiOCl nanocomposite photocatalyst. Background technique [0002] With the continuous development of urbanization and industrialization, the problem of environmental pollution has become increasingly prominent, especially the impact of organic pollutants (such as methyl orange, etc.) on water bodies, which has seriously affected human health and living environment, and has become a problem that we cannot ignore. Therefore, how to remove such pollutants has become a top priority. Photocatalytic degradation has been widely used in environmental pollution control due to its high-efficiency performance, green environmental protection, and economical feasibility. However, due to the wide band gap of most photocatalysts, th...
