Synthesis and diagnostics of porous glass with gold particles
Incoming article date: 25.09.2016In the present work the mesoporous transparent silica monolith with surface area of 650 m2/g was obtained by sol-gel method. Introduction of gold salt into reaction mixture allowed to form micro- and nanoparticles of gold in monolith's volume by rising the temperature. The obtained composite was stabilized by activation in air at 600 °C. It is an useful model for investigation of optical and catalytical properties of noble metal particles.
