Metal ceramic nanotubular structures for high temperature applications

Kurzfassung

In the present research proposal it is intended to produce a Ti-TiO2-MxOy metal ceramic nano-tubular composite with large surface area for applications as catalysts (i.e. automotive, oxidation catalysts) and for energy storage (i.e. electrodes) or gas-sensors. High surface area surfaces will be synthesized by the anodic oxidation of titanium. It is intended to correlate the process parameters of the anodization with the structure of the nano-composite. The improvement of the thermal resistance of the nano-tubular composite is expected upon the nano-structure modification. Additional approaches such as coating by means of the sol-gel method and galvanic coating are proposed to modify the nano-tubular structure and thus its thermal resistance. Finally, of major importance is to test the performance of the nanostructured surfaces as catalysts, electrodes and/or gas-sensors.
