Abstract:
The glancing angle deposition (GLAD) method is a kind of physical vapor deposition and many kinds of self-standing nanostructured materials can be prepared. Here we report GLAD method to form self-standing TiO2 nanostructures on specific substrates, which makes photocatalysts easier to recycle. And smart designs of doping, decorating band gap matched materials can also make traditional photocatalysts take use of more visible light. In this review, we present some previous work fabricating nanostructured TiO2 composites for enhanced photocatalytic performance by these methods.
Key words:  glancing angle deposition  TiO2  photocatalytic  nanostructure
