Carbon nanotubes have witnessed a great scientific interest during the last decade since their
discovery as a by-product in the arc discharge materials in 1991 [1]. Consecutively to their
discovery, studies rise on the use of these new nanomaterials in the field of an exciting
nanotechnology. Since there numerous potential applications of carbon nanotubes in several
domains have been demonstrated covering from the electronic to energy storage devices [2-3].
Among these different potential applications the most promising field seems to be the
catalysis field according to recent publications [4-6]. Their specific characteristics offer
advantages such as high external surface area, high specific surface area, good electrical and
thermal conductivity as well as their high resistance towards acidic or basic media.
The present article is focused on the large scale synthesis of these carbon nanotubes [7] and
their structural modification after thermal treatment at high-temperature. The surface
behaviour of these nanomaterials will be evaluated in a liquid-phase reaction, i.e., oxidative
dehydrogenation of dihydroanthracene into anthracene at relative low reaction temperature.
The MWNTs before and after the thermal treatment were characterised by, TEM, SEM,
Raman, XPS and surface area analysis (Figure 1).
