Abstract: front page image
(EN)Preparing porous particles includes forming a gel including a first liquid and an oxygen-containing compound of a metal, semi-metal, metalloid, or semi-conductor, including an oxide, hydroxide, alkoxide, oxohydroxide, oxoalkoxide, oxo salt, or oxo salt hydrate of the metal, semi-metal, metalloid, or semi-conductor; contacting the gel with a combustible liquid to form a combustible gel; and initiating combustion of the combustible gel to form a substance including porous metal, semi-metal, metalloid, or semi-conductor oxide particles. The combustible liquid can include a volatile solvent. The porous particles have open pores with a range of nanoscale pore sizes. The porous particles may be treated further to form, for example, a composite.
(FR)L'invention porte sur la fabrication de particules poreuses comprenant la formation d'un gel comprenant un premier liquide et un composé contenant de l'oxygène d'un métal, d'un semi-métal, d'un métalloïde ou d'un semi-conducteur, comprenant un oxyde, hydroxyde, alcoolate, oxohydroxyde, oxoalcoolate, sel d'oxo ou hydrate de sel d'oxo du métal, du semi-métal, du métalloïde ou du semi-conducteur; la mise en contact du gel avec un liquide combustible pour former un gel combustible; et l'amorçage de la combustion du gel combustible pour former une substance comprenant des particules poreuses d'oxyde de métal, de semi-métal, de métalloïde ou de semi-conducteur. Le liquide combustible peut comprendre un solvant volatil. Les particules poreuses ont des pores ouverts avec une gamme de dimensions de pore à l'échelle nanométrique. Les particules poreuses peuvent être encore traitées pour former, par exemple, un composite.
