Spherical Co-doped SiO2/Cu-grafted TiO2 hybrid particles were prepared using organic spherical monolith particles as a template. Rutile was crystallized in the monolith particles impregnated with a TiO2 precursor solution by hydrothermal treatment in a strong acid condition (2M HCl). Subsequent UV illumination assisted efficient decomposition of organic compounds in the particles during firing. The...
Porous spherical Co-doped SiO 2 /TiO 2 hybrid particles were prepared using two-step impregnation (CS/T(i)) or impregnation and subsequent spraying of precursor solutions (CS/T(s)) to organic spherical monolith particles. The hybrid particles, after firing at 550°C in air, possessed intermediate specific surface area and pore structure characteristics that were between those of Co-doped...
