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 {\^A}oC. When thetemperature exceeded 870 {\^A}oC, 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. {\^A}{\copyright} 2016 The Authors.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85013904406&doi=10.1016\%2fj.proeng.2016.06.563&partnerID=40&md5=43cf85686b217c5d76dfc0efa90de10c}, issn = {18777058}, author = {Iqbal, F. and Mutalib, M.
