| Abstract |
| A greener water treatment technique is required to eliminate the hazardous and carcinogenic chemicals such as pesticides, insecticides, etc from contaminated water. Photocatalysis based on titania are the excellent materials to achieve complete degradation of the agro chemicals. In this work, nanocrystalline titania and strontium titanate have been synthesized by sol-gel process. Doping of titania based catalysts with metal or non-metal elements decreases the bandgap and hence increases the photo efficiency. Synthesized titania and strontium titanate have been doped by multielements (C, N, B, F) and Ni/Ru respectively. The catalysts have been characterized by XRD, UV-DRS, SEM and TEM. The synthesized catalysts have been tested for their catalytic activity towards the degradation of carcinogenic insecticide imidacloprid using multilamp photo reactor. The reaction parameters such as initial concentration of insecticide, catalyst weight and pH have been optimized and the results were discussed. |
