A catalyst precursor composition and methods for making such catalyst precursor is disclosed. In one embodiment, the catalyst precursor is of the general formula Av[(MP)(OH)x(L)ny]z(MVIBO4), wherein MP is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof; L is one or more oxygen-containing ligands, and L has a neutral or negative charge n<=0, MVIB is at least a Group VIB metal having an oxidation state of +6; MP:MVIB has an atomic ratio between 100:1 and 1:100; v-2+P*z-x*z+n*y*z=0; and 0<=y<=-P/n; 0<=x<=P; 0<=v<=2; 0<=z. In one embodiment, the catalyst precursor further comprises a cellulose-containing material. In another embodiment, the catalyst precursor further comprises at least a diluent (binder). In one embodiment, the diluent is a magnesium aluminosilicate clay.
