Abstract:Rutile TiO2 nanowires anchored on silica were fabricated by annealing TiO2 nanoparticles dispersed on silicon or quartz substrate by means of a polystyrene nanosphere monolayer template at 1000 °C for 1 h without any catalyst. The diameter and length of the nanowires were 30–80 nm and 1–3 m, respectively. The growth direction of the nanowires is . The photocatalytic activities of TiO2 nanoparticles and anchored nanowires were evaluated. TiO2 nanowires had higher photocatalytic activity for rhodamine B than TiO2 nanoparticles.
