Figure 1

(a–d) Schematic illustration for depositing TiO2 NPs on suspended CNTs. (e) TEM images of CNTs with small TiO2 NPs prepared with contact time of 0.1–0.3 s. Scale bar, 200 nm. (f) TEM image of CNT with TiO2 NPs with various sizes prepared with contact time of 7.0 s. Scale bar, 500 nm. Inset: high-resolution TEM image of the CNT shown in panel f. Scale bar, 5 nm. (g,h) SEM images of suspended CNTs decorated with TiO2 NPs prepared with contact time of 5.0 s. Scale bar, 10 μm (in g); 2 μm (in h).
