The anatase phase of Tio2 nano particles calcined at 250 C was confirmed by PXRD analysis. The UV-vis spectra reveal the cutoff wavelength of pure and pre dye treated Tio2 as 356 nm and 408 nm respectively. The band gap of pre dye treated Tio2 is reduced to 3.02 eV compared to 3.48 eV of pure Tio2. The FTIR spectra confirm the functional groups of pure and pre dye treated TiO2. The SEM images confirm the improvement in morphology and reduction in agglomeration due to pre dye treatment.
