Deep Oxidative Desulfurization of Dibenzothiophene by Functional Tungsten-Containing Mesoporoussilica from Polyoxometalate-Based Salts

Abstract:

Tungsten-containing functional mesoporousW-SiO₂ have been successfully synthesized by an one-pot and facile room-temperature procedure. These materials presented a high dispersion of tungsten species and excellent catalytic activity on the removal of sulfur compounds without any organic solvents as extractants. The catalytic performance on sulfur compounds was investigated in detail. After recycling for 8 times, the removal of the oxidation desulfurization system could still reach 92.0%.
