Abstract
Relatively disordered mesoporous particulate materials have internal porosity, a surface area of 100 m2/g or greater with a network of pores characterised by a peak in the pore size distribution at a value between 2 and 20 nm and a ratio of the half-height width of the distribution's peak to the pore diameter axis position of the peak of at least 0.6.
Claims25
A mesoporous particulate material having internal porosity, a surface area, in the case of a metal, of at least 30 m2/g or, in other cases, of at least 100 m2/g with a network of pores characterised by a peak in the BJH pore size distribution in the range from 2 to 20 nm and a disorder ratio, as defined, of at least 0.6.
A process for the preparation of a mesoporous particulate material formed of a first compound or an element, which process comprises:
- forming a mixture comprising a second compound from which the first compound or element may be deposited, a solvent and a surfactant in amounts sufficient to form a liquid crystal phase in the mixture;
- and
- depositing the first compound or the element from the second compound, under conditions of concentration, reaction time and reaction temperature such as to form a mesoporous particulate material
- wherein the resulting particles have internal porosity characterised by a disordered pore structure, a surface area, in the case of a metal, of at least 30 m2/g or, in other cases, of at least. 100 m2/g with a network of pores characterised by a peak in the pore size distribution between 2 and 20 nm and a disorder ratio of at least 0.6.
