%X This study aims to synthesize a low band gap semiconductor that will able to convert higher band gap semiconductor under visible light driven photocatalyst. P-type Zinc ferrite (ZnFe2O4) particles were synthesized by a sol-gel method in acidic medium. A stoichiometric amount of zinc nitrate (Zn (NO3)2.4H2O) and ferric nitrate (Fe (NO3)3.9H2O were used. Thermogravimetric analysis (TGA) was performed to study a weight loss at higher temperatures and UV - VIS to determine the minimum wavelength of lightrequired for the activation of the synthesized catalyst. TGA illustrated that maximum weight loss occurs in the temperature range 200-700 °C. When thetemperature exceeded 870 °C, no further decomposition of sample occurred. Absorbance pattern of ZnFe2O4 synthesized under two different conditions (i.e. under N2 gas atmosphere and under normal atmosphere) showed a similar absorbance pattern in wavelength ranges from 380-590 nm but from 590-800 nm, the sample calcined under N2 gas environment exhibits higher absorbance than the sample calcined under atmosphere condition. © 2016 The Authors.
