The invention relates to a composite material constituted by a microporous or mesoporous matrix and nanoparticles of metal or of metal oxide. The material being wherein the material of the matrix is either disordered, or ordered and optionally oriented, and wherein the nanoparticles are i) monodisperse in size when said matrix material is ordered and optionally oriented; ii) either monodisperse in size or of size identical to the size of the pores of the matrix material when said matrix material is disordered. The method of preparing the material consists in impregnating a microporous or mesoporous solid material with a solution of nanoparticle precursors, then in reducing the precursors within said material forming the matrix. Impregnation is performed under saturated vapor pressure and under reflux of the precursor solution, and reduction is performed radiolytically.
A method of preparing a composite material, the method consisting in impregnating a microporous or mesoporous solid material with a solution of one or more precursors of metallic nanoparticles or of metal oxide nanoparticles, then in reducing the precursors within said matrix-forming material, the method being wherein impregnation is performed under saturated vapor pressure and under reflux of the precursor solution, and wherein the reduction is performed radiolytically.
A composite material constituted by a matrix constituted by a microporous solid material having pores with a mean size less than one nanometer or by a mesoporous solid material having pores with a mean size in the range 1 nm to 100 nm, and by nanoparticles of metal or of metal oxide, the material being wherein the material of the matrix is either disordered, or ordered, and optionally oriented, and wherein:
