摘要: Abstract Porous spherical Co-doped SiO2/TiO2 hybrid particles were prepared using two-step impregnation (CS/T(i)) or and subsequent spraying of precursor solutions (CS/T(s)) to organic monolith particles. The particles, after firing at 550 °C in air, possessed intermediate specific surface area pore structure characteristics that between those SiO2 porous TiO2 ones. crystalline phase was anatase. CS/T(s) decomposition activity against gaseous acetaldehyde both the dark under UV. ratio position are expected be key factors for overall performance.
