Abstract

The technological and economic importance of photocatalysis has increased considerably over the past decade. Improvements and performance have been strongly correlated to advances in nanotechnology. The introduction of nano particulate photocatalysts has tremendously enhanced the catalytic efficiency of specific materials. Photocatalysis based on nano catalysts is a very promising method for the treatment of contaminated water. Nano sized anatase TiO₂ particle was prepared by time consuming cost effective sol-gel method, the synthesized particles was examined and their characteristics were investigated. The average grain size of the nano particle is nearly 20nm. The UVVisible spectrum shows the absorbance of 356 nm which shows the band gap 3.7 eV. Photocatalytic activity of nano particle was evaluated by photo degradation of Methylene blue.
