Abstract:
1. A method of producing porous complex oxides comprising a metal oxide phase containing two or more metallic elements homogeneously distributed in the oxide phase, at least one of the metals selected from a non-refractory metal selected from metals of atomic number 3, 4, 11, 19-21, 23-32, 37-39, 41-51, 55-84 and 87-103, the method including forming a mixture of: a) precursor elements suitable to produce the complex oxide; or b) one or more precursor elements suitable to produce particles of the complex oxide and one or more metal oxide particles; wherein at least one of the precursor elements is present in the form of a solution; and c) a solid particulate carbon-containing pore-forming material selected to provide pore sizes in the range of approximately 7 nm to 250 nm, said solid particulate carbon-containing pore-forming material being dispersed throughout the mixture; and d) one or more surfactants present in an amount sufficient to form micelles; and heating the mixture to
