Title

Comparative Functionalization of CNT by oxy-nitride nanoparticles, using high power pulse plasma assisted vapor deposition (HIPIMS) or Laser Pyrolysis.

Abstract

The energy demand is growing but is fronting the global warming and the reduction of fossil and mineral resources. In order to solve that conflicting evolution, we must develop techniques fast for the production of renewable energy, such as solar energy and also reduce the amount of material required in systems such as fuel cells. This reduction requires the use of nano-powders, since the surface-to-volume ratio increases when the diameter decreases.

In this framework, we propose to conduct a study of the Functionalization of conductive porous surfaces, such as aligned carbon nanotubes, by nitride and oxy-nitride nanoparticles. While pure oxide (Ta2O5, TiO2, etc.) have an optical gap in the UltraViolet, nitride and oxy-nitride have a gap in the field of the visible, where the solar emission is maximum, ranging from infra-red to the blue, following their stoichiometry and their nanostructure.



Two types of Functionalization will be studied:

-Functionalization by pulsed plasma methods, developed in the laboratory of Physics of Gas and Plasma of the University Paris-Sud.

-Functionalization by nitride nanoparticles prepared by Laser Pyrolysis at the Laboratory Francis Perrin. The development of porous surfaces including nanotubes carpet and physical-chemical analyses will be carried out at the LFP, in collaboration with other teams of the IRAMIS CEA-Saclay
