RECENT DEVELOPMENTS IN METAL BASED PHOTOCATALYSTS – A REVIEW

Abstract

The problem of fresh water scarcity is growing all around the world due to the over utilization and pollution. Discharge of pollutants especially dye bearing wastewater drastically affects the life of flora and fauna. Finding a suitable technology for the treatment of wastewater is highly warranted in the present context. Photocatalytic degradation using metal and metal oxide composite has lot of advantages like negligible by-products, simple to operate and economically very cheap. This manuscript reviews the potential photocatalytic applications of Ti, V, Mn, Co, Cu, Zn, Ga, Zr, Pd, Sn and inner transition metal doped catalysts.
