Abstract
Novel N-doped CsTi2NbO7@g-C3N4 (NCT/CN) core-shell nanobelts were prepared by a facile one-step calcination method for the first time, in which [Ti2NbO7]− layers were in situ doped by nitrogen atoms, and g-C3N4 was formed both on the external surface and within the interlayers of N-CsTi2NbO7. The morphology, structure and visible-light photocatalytic activity of samples were studied and discussed in detail. The resulted NCT/CN composite showed an enhanced visible-light photocatalytic activity in the degradation of RhB, attributing to the synergistic effects of N-doping, morphology engineering and heterojunction formation.
