Abstract :
The Cu-doped hydrogen titanates nanotubes were prepared by hydrothermal process and subsequently ion-exchange reactions. The products were characterised in detail by multiform techniques: X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray analysis. These tubes are hollow scrolls with a typical outer diameter of 10-12-nm, inner diameter of about 6-nm and length of several hundreds nanometres. The photoluminescence and the adsorption properties of Cu-doped hydrogen titanates nanotubes have been systematically investigated.
