Indian Scientists have developed an efficient photocatalyst

A recent advancement in the field of environmental science highlights the development of a novel photocatalyst capable of effectively degrading broad-spectrum antibiotics, specifically sulfamethoxazole (SMX). Researchers at the Institute of Advanced Study in Science and Technology (IASST) in Guwahati, led by Prof. Devasish Chowdhury, have created nanoparticles of copper zinc tin sulfide (Cu₂ZnSnS₄, referred to as CZTS) and a composite made from CZTS combined with tungsten disulfide (CZTS-WS₂). This catalyst shows promise in transforming sulfamethoxazole into less hazardous substances, thereby addressing medical and ecological concerns related to antibiotic contamination in the environment.
