Abstract

Abstract:

NiO-TiO₂ coupled semiconductors were synthesized by organic templates method．Their pore distribution, crystal structure，surface composition and photo absorption properties were investigated by techniques of N₂ adsorptiondesorption, XRD, TPR, TEM and UV-Vis DRS. The results show that the NiO-TiO₂ coupled semiconductors prepared by organic templates exist in nanotube or nanobelt with mesporous structure, and the BET surface area is higher than 100m²/g. The NiO particles disperse well on the surface of TiO₂, and the strong interaction between NiO and TiO₂ results in the formation of NiTiO₃. The p-n couple effect of NiO and TiO₂ extends distinctly the photo absorption field and decreases the Eg from 3.82eV to 3.49eV when the addition amout of NiO is increased from 2% to 10%.

Key words: mesoporous, coupled semiconductor, NiO-TiO₂, photo absorption property
