Process for impregnating porous materials and process for preparing nanostructured product

The invention relates to a process for preparing a porous material comprising metal, metalloid, or non-metal precursor, said process comprising the steps of: - dispersing the porous material in a hydrophobic solvent; - adding a metal, metalloid, or non-metal precursor solution in a hydrophilic solvent to the dispersed porous material and the hydrophobic solvent, thereby forming a mixture; and - selectively removing the hydrophilic solvent from the mixture; thereby impregnating the porous material with the metal, metalloid, or non-metal precursor solution; thereby preparing a porous material comprising metal, metalloid, or non-metal precursor. The process may additionally comprise a step of converting the precursor, and a step of removing the porous material. Also described is a nanostructured metal, metalloid, or non-metal decomposition product; or metal, metalloid, or non-metal; or metal, metalloid, or non-metal oxide. ln a preferred embodiment, nanostructured bismuth is prepared using mesoporous silica or mesoporous titania as the porous material, viz. template.
