Abstract : A variety of single, bi and tri metal doped TiO 2 nanoparticles were prepared by sol-gel method and analysed for their adsorption and photocatalytic abilities using Methylene Blue (MB) as target pollutant. The materials were characterised using XRD, ESD, SEM, FT-IR, FL microscopy and DRS. A very simple, low cost, efficient and robust physical heterostructure of Ag 3 PO 4 /TiO 2 was also successfully developed. The composition, optical properties and morphology of the prepared nanomaterials were controllable by adjusting the mixing ratios. The physical mixture exhibited much higher photocatalytic performance under the visible light as well as adsorption capacities. The coupling of Ag 3 PO 4 particles with UV light active TNPs simultaneously could utilize the larger part of solar spectra and less consumption of metals. The heterostructure is quite appealing for their practical use in environmental issues. Further, this provides an easy, rapid and low cost adsorbent and a good photocatalyst which otherwise is costly and time consuming when synthesised chemically. Keywords— Adsorption, Methylene blue, Mixture, Photocatalysis, Titania.
