Description: A new amphipathic lindqvist-type polyoxometalate-based TiO.sub.2 nanofibres catalysts (50-DTA-MoO-TiO.sub.2NF, DTA = CH.sub.3(CH.sub.2).sub.11(CH.sub.3).sub.3N, MoO = Mo.sub.6O.sub.19.sup.2-, TiO.sub.2 NF = TiO.sub.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 The amphipathic lindqvist-type polyoxometalate-based TiO.sub.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.sub.2NF as catalyst in 40 min with O/S molar ratio of 2:1 in ECODS.
