Abstract

Material compuesto que comprende una matriz porosa de carbón amorfo y nanopartículas de Bi obtenible mediante un procedimiento sol-gel, procedimiento de obtención y su uso.#La presente invención se refiere a un material compuesto que comprende una matriz porosa de carbono amorfo con un tamaño de poro comprendido entre 2 y 1000 nm, en la que se encuentran embebidas y distribuidas homogéneamente nanopartículas esféricas de tamaño comprendido entre 5 y 500 nm de al menos un elemento metálico que es Bi en fase cristalina tetragonal, obtenible mediante un procedimiento que comprende al menos las siguientes etapas:#a) preparar una composición líquida sol-gel en forma de solución que contiene al menos un precursor orgánico de la matriz en un solvente;#b) depositar la solución líquida dentro de un molde o sobre un soporte en forma de capa o microestructura;#c) condensar la solución líquida que contiene el precursor orgánico en el molde o en el soporte, hasta dar lugar a un gel orgánico húmedo;#d) secar el gel húmedo; y#e) someter el gel a pirólisis, en atmósfera inerte a una temperatura igual o superior a 800°C;#donde al menos un precursor del Bi se adiciona en la primera etapa a) disolviéndose en el solvente junto al precursor orgánico para formar parte de la composición sol-gel, o se adiciona en la tercera etapa c) impregnando el gel orgánico húmedo con una solución del precursor de Bi en un solvente antes del secado; y donde el material presenta un área superficial de Bi comprendida entre 2.5-10{sup,2} cm{sup,2}/g y 2.5-10{sup,5} cm{sup,2}/g, la matriz presenta una porosidad intrínseca accesible comprendida entre 10% y 95% respecto al carbono amorfo no poroso.
