Abstract	Polyoxometalates (POMs) possess unique strong Brønsted acidity. However, little attentions has been paid to the effect of POMs with respect to the hydrocracking. Authors explain that Wells–Dawson type POMs Cs5.5H0.5P2W18O62 (CsDP) combined with conventional Fischer–Tropsch catalyst Co/Al2O3 forming a highly efficient bifunctional catalyst for the direct production of clean gasoline from syngas. The Brønsted acidity of the CsDP results in hydrocracking of the heavier hydrocarbons formed on Co/Al2O3. The selectivity for the gasoline product could reach 48.8%, which has increased by 129% than that of conventional FTS catalyst. In addition, they compare the catalytic performance of Wells–Dawson type POMs Cs5.5H0.5P2W18O62 with Keggin type POMs Cs2.5H0.5PW12O40 based catalyst. The former exhibits higher CO conversion and C5–C12 selectivity than those of the Keggin type of Cs2.5H0.5PW12O40.
