A visible‐light‐driven photocatalyst based on the well‐known cathode material of NASICON ‐type Li 2 Ni 2 (MoO 4 ) 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 Li 2 Ni 2 (MoO 4 ) 3 particle is below 50 nm. NASICON nanoparticles Li 2 Ni 2 (MoO 4 ) 3 has an efficient absorption in the UV ‐visible light wavelength region with a direct allowed electronic transition of 2.07 eV. The photocatalytic properties of Li 2 Ni 2 (MoO 4 ) 3 were evaluated by the photodegradation of methylene blue ( MB ). Li 2 Ni 2 (MoO 4 ) 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 MoO 4 and NiO 6 and its good conductivity.
