TY - JOUR ID - TI - Photocatalytic Performance of Mixed and Single Phases of Titanium Dioxide Nanoparticles on Growth of Fusarium Oxysporum Fungal AU - Maryam A. Nima, Firas J. Kadhim PY - 2021 VL - 17 IS - 4 SP - 9 EP - 14 JO - Iraqi Journal of Applied Physics المجلة العراقية للفيزياء التطبيقية SN - 18132065 23091673 AB - In this work, the photocatalytic activity was considered to inactivate Fusarium oxysporum fungal under UV radiation exposure using highly-pure TiO2 nanoparticles. These nanoparticles were extracted from thin film samples prepared by dc reactive magnetron sputtering system. The mixed-phase (anatase+rutile) films were prepared using two different gas mixing ratios and different deposition times (3, 3.30 and 4 hours). Accordingly, the weight fractions of rutile in mixed-phase were 40, 46 and 50%, respectively. The single phase (anatase) was produced without any heat treatment using specific mixing ratio of 50:50. The structural and spectroscopic characteristics of the prepared nanoparticles were determined and analyzed. At weight fraction of 40% of mixed-phase TiO2, the best antifungal activity was achieved.
