Biopolymer based photocatalysts and their applications

Photocatalysis is an innovative practical technique which has been widely used to overcome environmental challenges. Photocatalysts are chemically activated upon exposure to ultraviolet irradiation that causes degradation and even demineralization of pollutants. So far, studies have been focused on...
