    The layered structure of H4Nb6O17 prepared by the proton exchange of K4Nb6O17 was modified by using various n-alkylamines as swelling agents to enlarge the interlayer space. The incorporation of TiO2 into the interlayer space was also attempted. XRD, EDX, and TG-DTA measurements were employed to characterize the products. The photocatalytic activities were evaluated by NOx destruction under photo-irradiation with different light wavelengths. The results showed that the photocatalytic activity of a layered compound could be significantly promoted just by enlarging the interlayer space of it. And the incorporation of TiO2 could further enhance the activity.
