Molybdenum-containing dendritic mesoporous silica spheres for fast oxidative desulfurization in fuel

Abstract

Desulfurization in fuel becomes more and more imminent due to increasingly stringent environmental protection policies. Mesoporous materials have attracted wide attention owing to their excellent ability in various catalytic reaction. Herein, we reported a synthesis of molybdenum-containing dendritic mesoporous silica spheres via a facile Stöber approach and employed in the removal of organic sulfur compounds. The dendritic mesoporous silica spheres not only provide the large specific surface area and pore volume but also possess a high dispersion of molybdenum species. Under the optimal conditions, the sulfur removal of refractory aromatic sulfur compounds 4,6-DMDBT can reach 100% in 40 minutes with a low dosage of oxidant. The catalysts can be reused for nine times without significant decrease. Furthermore, the oxidative desulfurization process was proposed through by gas chromatography-mass spectrometer (GC-MS).
