In this work, detail investigation on UV photocatalytic dye decomposition activity is done with Zinc Orthotitanate (Zn2TiO4) nanoparticles grown by solid state reaction method and shown that these nanoparticles can show 6 times higher activity than standard commercial TiO2 nanoparticles Degussa P25. This activity is the highest among all the nanoparticles that have been compared with P25 so far. The potential cause for higher activity is explored through absorption spectroscopy. The Zn2TiO4 nanoparticles are prepared from laboratory grade ZnO and TiO2 powder of extremely low cost. Excellent recycling ability of Zn2TiO4 nanoparticles is shown through their multiple usages. © 2018 Elsevier B.V.
