| Abstract: | In this study, hollow titania film (HTF) was prepared by a sol–gel spin-coating technique using titania coated nano carbon spheres as precursor suspension. The carbon spheres were synthesized by hydrothermal method using glucose as precursor. Photoelectrochemical property of HTF was examined by anodic photocurrent response, and results showed that the photocurrent of HTF was nearly twice as that of compact titania film (CTF). The photocatalytic and photoelectrochemical applications were investigated by using HTF or CTF as photoanodes for X-3B degradation under UV irradiation. Results showed that photocatalytic and photoelectrochemical activity of HTF enhanced a lot compared to CTF. |
