采用一步煅烧法制备了新型的N掺杂CsTi 2NbO 7 @ g-C3 N4（NCT/CN）核壳纳米带，在[Ti 2NbO 7]−层中原位掺杂N原子，在N-CsTi 2NbO 7的外表面和层间形成g-C3 N4。对样品的形貌、结构和可见光催化活性进行了详细的研究和讨论。NCT/CN复合材料在可见光催化降解罗丹明B中表现出更高的活性，这归因于N掺杂、形貌工程和异质结形成的协同效应。
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-C3N4was 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.
