ResumoAbstract A novel TiO 2− x N x /CNFs heterostructured photocatalyst was facilely fabricated by stabilization, NH 4 OH pretreatment and carbonization of electrospun TiO(OAc) 2 /PAN hybrid nanofibers. The uniformly aligned CNFs were interspersed with 25 wt% of anatase TiO 2− x N x nanoparticles, in which the x value or doped N atomic ratio was ∼0.52%. The TiO 2− x N x /CNFs had a considerable surface area of 130 m 2 /g and extraordinary mesoporous morphology. Owing to the synergistic effect between high adsorption capacity of CNFs and excellent vis-photocatalytic activity of TiO 2− x N x nanoparticles, the TiO 2− x N x /CNFs showed higher photocatalytic efficiency than referenced TiO 2 /CNFs and TiO 2− x N x powders.
