Summary:•N and V co-doped TiO2 mesosponges were prepared by hydrothermal method.•The first-principle was used to investigate the novel porous materials.•N-V-TMSW had a remarkable visible absorption and photocatalytic activity. Novel N and V co-doped TiO2 mesosponge (N-V-TMSW) layers were successfully prepared by one-step hydrothermal treatment of TiO2 nanotube arrays, and the phase composition, morphology and optical property were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force microscope (AFM), X-ray photoelectron spectroscopy (XPS) and UV–vis diffusion reflectance spectroscopy (DRS). The crystal structure and density of states were studied by means of the first-principle pseudo-potential plane wave. The results indicated that titanium ions and oxygen atoms in TiO2 were successfully substituted by vanadium ions and nitrogen atoms, respectively. The sample N-V0.1-TMSW showed a remarkable absorption in the visible light range of 400–600nm and high visible photocatalytic activity
