It is of great importance to develop efficient catalysts to achieve sulfur removal in fuel, protecting the world against the pollution caused by sulfur oxides. Aiming that, polyoxometalates supported materials have been employed as a vital class of heterogeneous catalysts for oxidative desulfurization. In this study, a serial of magnetic polyoxometalates-based mesoporous silica hybrid materials were...
Shengli lignite (SL) was oxidized and depolymerized in aqueous sodium hypochlorite under mild conditions followed by sequential extraction with ethoxyethane and ethyl acetate. The extracts were analyzed by Fourier transform infrared spectroscopy, gas chromatograph/mass spectrometry (GC/MS), time-of-flight mass spectrometry (TOF-MS) equipped with electrospray ionization (ESI), and direct analysis in...
