Abstract

Spherical mesoporous graphitic carbon nitride (g-C ₃ N ₄ ) was successfully prepared through spherical mesoporous silica as sacrificial templates, and analyzed by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, thermogravimetric analyzer, N ₂ adsorption-desorption isotherm, BET, UV–vis diffuse reﬂectance spectra and photoluminescence spectra. Experimental results indicated that as-prepared g-C ₃ N ₄ exhibited spherical morphology with high surface area due to the introduced porous structure, which made the as-prepared g-C ₃ N ₄ possess much higher activity than the bulk g-C ₃ N ₄ for producing H ₂ and decomposing rhodamine B (RhB) under visible light, and it also kept excellent recycling activity. Hence, this investigation provided a simple strategy for the fabrication of porous special morphology graphitic carbon nitride with excellent photocatalytic activity.
