Non-hydrolytic sol-gel synthesis of mesoporous iron-aluminum oxide and their properties in the oxidation of hydrocarbons by hydrogen peroxide
[EN] Iron-containing alumina materials were prepared by the non-hydrolytic sol-gel method in the presence of surfactants and their use as catalysts in the oxidation of hydrocarbons was studied. The solids were mesoporous, with large specific surface areas, > 250 m2 /g for the solids treated at 50...
