摘要：In this study, hybrid materials carbon-doped ordered mesoporous silica containing tungsten species were successfully synthesized through one-pot selfassembly process, and employed as catalysts for heterogeneous oxidative desulfurization of aromatic organic sulfur compounds. Various techniques such as vibrational spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller method, Transmission electron microscopy, and Energy dispersive X-ray spectroscopy were employed to study the structure and composition of catalysts. The sulfur removal could reach 100% in 30 min under mild conditions. It was also found that carbon-doping could play an important role in retaining ordered mesoporous structure in the silica framework. The sulfur removal of the catalyst could still reach over 90% after recycling for ten times, indicating an approved prospect toward potential application.
