The Ultra-Deep Desulfurization of Model Oil Using Amphipathic Lindqvist-Type Polyoxometalate-Based TiO2 Nanofibres as Catalysts

Abstract A new amphipathic lindqvist-type polyoxometalate-based TiO 2 nanofibres catalysts ( 50-DTA-MoO-TiO 2 NF , DTA = CH 3 (CH 2 ) 11 (CH 3 ) 3 N, MoO = Mo 6 O 19 2- , TiO 2 NF = TiO 2 nanofibres, the weight percentage of DTA-MoO was 50%) was obtained by electrospinning and applied in desulfurization of fuel. This catalyst presented outstanding desulfurization performance and reusability. Graphic Abstract The amphipathic lindqvist-type polyoxometalate-based TiO 2 nanofibres were prepared successfully and examined as heterogeneous catalysts in removal of sulfur-containing compounds. At 333 K, 100% desulfurization efficiency of 500 ppm DBT model oil was achieved using 0.010 g 50-DTA-MoO-TiO 2 NF as catalyst in 40 min with O/S molar ratio of 2:1 in ECODS.
