STUDIES ON UVVISIBLE LIGHT RESPONSIVE METAL oxide NANO COMPOSITES AS PHOTOCATALYST

Abstract

An extensive literature survey (Chapter I) on water pollution suggested that dyes and newlineinorganic pollutants are responsible for the contaminating the water body. Finding right kind newlineof photocatalyst that can adsorbs or degrade the pollutant is a challenge. As the literature newlinereview shows though enormous work has been done in photocatalysis still lot of research is newlinebeing conducted in order to find right kind of catalyst. Single catalyst can t remove every newlinekind of dyes and pollutants present in the waste water. Though UV light can also initiate the newlinephotocatalysis process still Visible light driven photocatalysis is desirable to expand newlineapplicability under solar irradiation. As discussed in the literature review tuning the band gap newlineby controlling size and shape, non-metal doping, making composite newline
