Degradation of methylene blue via Co–TiO2 nano powders modified by meso-tetra(carboxyphenyl)porphyrin
Source abstract
Abstract
TiO2 photocatalylysts as an environmental cleaning factor has drawn considerable attention due to the global increase in the level of environmental pollutions. Studies on the development of new TiO2 materials wherein its photocatalytic activity can be activated by visible light will be valuable for field application. In this study, porphyrins/Co-doped TiO2 were prepared by sol–gel method. The nanopowders were characterized by means of X-ray diffraction, energy dispersive X-ray spectroscopy, IR spectroscopy and transmission electron microscopy (SEM). In addition, the photocatalytic degrading efficiency of porphyrins/Co-doped TiO2 complexes on the methylene blue decomposition under irradiation with visible light is evaluated.
