Method for preparing nanoparticles of titanium dioxide modified with precious metals such as platinum, silver and gold, in particular for photocatalysis

摘要

process to obtain titanium dioxide nanoparticles modified with precious metals like platinum, silver and gold, especially to fotokatalizy is characterized by the fact that at the bottom of the vessel (4) filled with deionised water (5) is placed plate (6) which illuminates the titanium to impu lsowu0105 a laser beam in a specified time, while in the process of the stablewhite relevant formed by nanoparticles of tio2. successively, in place of titanium plates placed plate with the selected metal and continues to illuminate the laser beam parameters of similar, as in the case of titanium plates in a set period of time, while in the process of receiving tio2 nanoparticles modified noble metal.the degree of modification of nanoparticles by precious metal closely depends on the duration of a laser beam illumination plate metal. nanoparticles doped with precious metals, may be used to fotokatalizy organic pollutants as well as to produce hydrogen by decomposition of water.
