A series of M(Ni, Zn, Co)-Ti LDHs are synthesized by urea method and are characterized by XRD and SEM. The results reveal that the M(Ni, Zn, Co)-Ti LDHs have high crystallinity. UV-Vis-DRS study confirms that Zn-Ti LDHs show a broad absorption in invisible light region. Compared with commercial TiO2, three kinds of LDHs all display a better photocatalytic activity for the degradation of methylene blue under 500 W xenon lamp (simulated sunlight) irradiation. It implies that all three kinds of LDHs have a visible light photocatalytic activity, in which Zn-Ti LDHs has the best activity. 99.8% of degradation rate of methylene blue can be achieved when the amount of catalyst is 20 mg and irradiation time is 4 h.
