CNTs-Modified Nb₃O₇F Hybrid Nanocrystal towards Faster Carrier Migration, Lower Bandgap and Higher Photocatalytic Activity.

ABSTRACT: Novel semiconductor photocatalysts have been the research focus and received much attention in recent years. The key issues for novel semiconductor photocatalysts are to effectively harvest solar energy and enhance the separation efficiency of the electron-hole pairs. In this work, novel Nb₃O₇F/CNTs hybrid nanocomposites with enhanced photocatalytic activity have been successfully synthesized by a facile hydrothermal plus etching technique. The important finding is that appropriate pH values lead to the formation of Nb₃O₇F nanocrystal directly. A general strategy to introdue interaction between Nb₃O₇F and CNTs markedly enhances the photocatalytic activity of Nb₃O₇F. Comparatively, Nb₃O_7<
