A visible-light-driven photocatalyst based on the well-known cathode material of NASICON-type Li2Ni2(MoO4)(3) was prepared by a modified Pechini method. The sample was characterized by X-ray diffraction, scanning electron microscope, transmission electron microscopy, and UV-vis absorption spectrum. The average size of Li2Ni2(MoO4)(3) particle is below 50nm. NASICON nanoparticles Li2Ni2(MoO4)(3) has an efficient absorption in the UV-visible light wavelength region with a direct allowed electronic transition of 2.07eV. The photocatalytic properties of Li2Ni2(MoO4)(3) were evaluated by the photodegradation of methylene blue (MB). Li2Ni2(MoO4)(3) has an efficient photocatalytic activity and could be a potential photocatalyst driven by visible-light. The photocatalytic activity was discussed on the optical absorption and special hexagonal tunnel structure connected by optical active centers of MoO4 and NiO6 and its good conductivity.
