Claim Text:
1. A hydrodesulphuration process of at least one gasoline cut implementing a catalyst comprising, in its oxide form, at least one metal from group VIB and/or at least one metal from group VIII of the periodic table present in the form of at least one polyoxometalate which is a Keggin heteropolyanion of the formula XM 12 O 40 q− , or a lacunary Keggin heteropoylanion of the formula XM 11 O 39 q− , wherein X is an element selected from phosphorus (P), silicon (Si), boron (B), nickel (Ni) and cobalt (Co), the said element being taken alone, M is one or more element(s) selected from molybdenum (Mo), tungsten (W), nickel (Ni) and cobalt (Co), O is oxygen, and q is an integer within the range 1 to 20, the polyoxometalate being present within a mesostructured silicon oxide matrix having a pore size within the range 1.5 to 50 nm and having amorphous walls of thickness within the range 1 to 30 nm, the catalyst being sulphured before being implemented in the process, and the catalyst in its oxide form exhibiting a form of each of the elementary particles of which it is composed that is non-spherical.
