Abstract

Fe doped SiO 2 nano composites powders were synthesized by a reverse micelle and sol-gel process. The average particle size of the mixed sol was below 25 nm and well dispersed in the solution. TEM results show the microstructure of Fe doped SiO 2 composite was homogeneous and Fe was below 5nm and Fe well dispersed in ceramic nano particles. Fe doped SiO 2 composite membranes were fabricated by sol-gel process. It was observed that Fe doped SiO 2 composite membranes showed a crack-free microstructure and narrow particle size distribution even after heat treatment up to 500 °C. The average particle size of the membrane was 30-40nm, and the pore size of Fe doped SiO 2 nano composite membrane was below 10 nm. The particle size of Pt after heat treatment at 500 °C was below 8nm.
