Preparation, characterization, and photocatalytic activity of g-C<sub>3</sub>N<sub>4</sub>/SrTiO<sub>3</sub> composite
View through CrossRef
The g-C3N4/SrTiO3 composite was hydrothermally synthesized at 150 oC for 12 hours from a dispersed mixture of g-C3N4 and SrTiO3 in water, in which SrTiO3 was hydrothermally synthesized at 150 oC for 12 hours using strontium nitrate, propan-2-ol, titanium tetrachloride and sodium hydroxide as precursors without assistance of any surfactant; and g-C3N4 was prepared by pyrolysis of melamine at 520 oC. The properties of materials were characterized by various techniques such as X-ray diffraction (XRD), infrared spectra (IR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS). The photocatalytic activity of materials was assessed by degradation of methylene blue (MB) under visible light. The enhancement of photocatalytic activity of the g-C3N4/SrTiO3 composite compared to single components g-C3N4 and SrTiO3 was observed.
