摘要
Photocatalysis utilizing semiconductor oxides is being researched widely for the degradation of dyes. This examination depicts the visible light actuated photocatalytic degradation of azo dye, methyl orange, utilizing NiO/C3N4 hybrid photocatalyst. The NiO/C3N4 hybrid photocatalyst with differing weight percentage were effectively synthesized by a simple calcinations method. The synthesized materials were described using x-ray diffraction, Fourier-transform infrared spectroscopy, Scanning electron microscopy-Electron dispersive spectroscopy, High resolution transmission spectroscopy, UV–vis diffuse reflectance spectroscopy, Atomic absorption spectroscopy and Photoluminescence. The photocatalytic action of NiO/C3N4 hybrid photocatalyst was assessed by the removal of methyl orange under visible light illumination (>400 nm). The loading of NiO on C3N4 was confirmed by AAS analysis. It is discovered that 4 wt% of NiO loaded C3N4 photocatalyst demonstrated maximum photocatalytic action and its comparing removal rate of methyl orange is accomplished 50% higher than that of bare g-C3N4 photocatalyst. Moreover, 78% of total organic carbon (TOC) removal was obtained with 4 wt% of NiO/C3N4 hybrid photocatalyst in 50 min.
