Abstract

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 (2 M HCl). Subsequent UV illumination assisted efficient decomposition of organic compounds in the particles during firing. The solvent of the solution for Cu grafting affects the pore structure. Ethanol was more suitable than water for the particles prepared in this study. The hybrid particles, after firing at 500 °C in air, possessed decomposition activity against gaseous acetaldehyde both in the dark and under visible light.
