| Abstract: | The photoelectrochemical behavior and surface image of electrodeposited nanocrystalline TiO 2 films prepared under different conditions were studied by using photocurrent spectroscopy, transparent spectroscopy and scanning probe microscopy. The particle sizes of the nanocrystalline TiO 2 films electrodeposited from 0 05 mol/L TiCl 3+Na 2CO 3(pH=2 2) and from 0 05 mol/L TiCl 3+NaOH(pH=2 2) were about 50 100 nm. The photoelectrochemical behavior of the TiO 2 films was related to the surface structures. The TiO 2 film electrodeposited at 0 1 V vs. SCE in 0 05 mol/L TiCl 3+NaOH(pH=2 2) was of better photoelectrochemical conversion efficiency. It was shown that the photoelectrochemical behavior of nanocrystalline TiO 2 films was different from those of compact semiconductor electrodes. |
