Author(s): Prashanth KPN, Bhojya NHS, Harish KN, Viswanath R, Ravi HR and Sreepad HR

In this paper we are presenting the remarkable TiO2 nano photocatalytic material. The TiO2 nano thin flms were deposited on glass substrate using PV-EBE method as well as sol-gel spin coating technique. The existed specimen shows nano-sized crystalline anatase phase. The optical and photocatalytic properties of the EBE and SGD films were compared. The reflectance of the films increased with increasing calcinations temperature from 3000°C and 5000°C as a result of the growth of particles. The refractive index of the SGD films increased significantly from 1.78 to 2.118 after heating at 5000°C were as that of EBE films increased slightly from 1.9 to 2.1. SGD films exhibited better photo activity then EBE films this has been explained in terms of porosity and the formation of Ti3+ ions during calcination, where EBE films had better optical activity then SGD films.
