Results for tag: "Photocatalyst"

A photocatalyst is a type of catalyst that uses light energy to speed up a chemical reaction. It is a type of heterogeneous catalyst, meaning it is composed of two or more different materials. Photocatalysts are used in a variety of industries, including water treatment, air purification, and energy production. They are also used in the production of pharmaceuticals, food, and cosmetics. Photocatalysts are typically composed of a semiconductor material, such as titanium dioxide, and a photosensitizer, such as ruthenium. The semiconductor absorbs light energy, which is then used to activate the photosensitizer, which in turn initiates the chemical reaction. The photocatalyst market is growing rapidly due to the increasing demand for clean energy and air purification. The market is expected to continue to grow as more industries adopt photocatalysts for their production processes. Some of the major companies in the photocatalyst market include BASF, Evonik Industries, Umicore, and Johnson Matthey. Show Less Read more
