The hydroxylated inorganic oxide support is functionalized by grafting at least one type of polyhydrosiloxane oil having from 10 to 200 siloxane units, the grafting being provided, on the one hand, by covalent bonds formed from a dehydrogenation/condensation reaction between Si-H groups of the polyhydrosiloxane oil and free hydroxyls of the hydroxylated support and, on the other hand, by hydrogen bonds between hydroxyls of the hydroxylated support and oxygen atoms of the polyhydrosiloxane oil, which exhibits free SiH groups. |
