Mesoporous graphitic carbon nitride as photo-catalyst for oxidative desulfurization with oxygen

In this study, we present a simple but efficient photocatalyst of mesoporous graphitic carbon nitride (mpg-C3N4) that can activate molecular O2 to oxidize dibenzothiophene under visible light. The desulfurization rate of the simulated oil was 100% under optimal conditions at room temperature. Mpg-C3N4 is characterized using transmission electron microscopy, nitrogen adsorption–desorption isotherm, and X-ray diffraction.
