Barium Ferrites Loaded TiO2 Usage In Photocatalytic Degradation of Rhodamine B Under Visible Light

Abstract

In the present study, the barium ferrites sample was synthesizedby conventional citrate method asa first step, then it was used with different amounts in TiO2 synthesis via a soft hydrolysis method as a second step. Resulted photocatalyst samples were named as BaFts/TiO2. The samples were characterized by X-ray diffraction XRD , UV–vis diffuse reflectance spectra DRS and scanning electron microscopy SEM . The samples were tested in Rhodamine B degradation under visible light. Rhodamine B degradation efficiency was increased approximately 2.8 times with respect to the efficiency of the naked TiO2.

Görünür Işık Altında Rodamin B’nin Fotokatalitik Parçalanmasında Baryum Ferrit Yüklenmiş TiO Kullanılması

Abstract

B u çalışmada ilk basamakta baryum ferrit örneği klasik sitrat yöntemiyle sentezlenmiştir. İkinci basamakta bu örnek hidroliz yöntemi ile TiO sentezinde farklı miktarlarda kullanılmıştır. Elde edilen fotokatalizör örnekleri BaFts/TiO2 olarak adlandırılmıştır. Örnekler X-ışını difraksiyonu XRD , UV-görünür alan difüz reflektansı UV-vis DRS ve taramalı elektron mikroskobu SEM ile karakterize edilmiştir. Örnekler, görünür ışık altında Rodamin B parçalanmasında kullanılmıştır. Rodamin B’nin parçalanma etkinliği, yalın TiO2’in etkinliğine kıyasla yaklaşık 2.8 kat artmıştır
