Photocatalyst is a material that can speed up a chemical reaction when it's exposed to light. When photons of light interact with photocatalyst, it generates highly reactive molecules called reactive oxygen species (ROS). These ROS can then react with organic compounds in the air and break them down into harmless byproducts like carbon dioxide and water. This process, called photocatalysis, helps to purify the air and eliminate unpleasant odors. Photocatalyst technology has many applications in air purification, water treatment, and self-cleaning surfaces.
