Abstract
A method of preparing a titanium and niobium mixed oxide including the steps of: preparing a titanium and niobium mixed oxide in amorphous form by a solvothermal treatment of at least one titanium precursor and of at least one niobium precursor, mechanically crushing the titanium and niobium mixed oxide obtained at the end of the solvothermal treatment and calcinating the mixed oxide obtained after crushing.
