Heterogeneous photocatalysis is an upcoming field wherein a catalyst that gets activated when solar energyfalls on it, photo-degrades the organics present in the effluent into harmless water and carbon dioxide. However, most ofthe research in this field has been carried out on TiO2, which has a limitation of being able to utilise only the ultra-violetlight of the solar radiations only. Hence, to be able to utilise a wider range of the available radiations, research is nowbeing focussed on developing photocatalysts which work in the visible spectrum as well. This paper discusses the stateof-the-art in this area. The first part outlines the basic principles and mechanism of photocatalysis, while the second onediscusses in brief the methods in which visible-light photocatalytic materials can be synthesised and utilised that arecapable of yielding a higher overall efficiency of the process.
