AI Article Synopsis
- The study used temperature-programmed desorption-mass spectrometry to investigate the formation of low-molecular-weight products by the thermal reaction of carbon nanotubes (SWNTs and MWNTs) with water vapor.
- The findings suggest that MWNTs react with water similarly to graphite, while acid-oxidized SWNTs exhibit reactivity akin to polymerized C60 fullerene.
- The researchers identified molecular surface curvature and pyrolyzable defect groups as key factors affecting the reactivity of these carbon structures.
Article Abstract
We used temperature-programmed desorption-mass spectrometry to verify whether low-molecular-weight products can form by reacting thermally pretreated single-walled and multi-walled carbon nanotubes (SWNTs and MWNTs, respectively) with water vapor. The reactivity of MWNTs toward water is similar to the reactivity of graphite, whereas acid-oxidized SWNTs behave like polymerized C60 fullerene. We think the main factors influencing the reactivity are molecular surface curvature and the presence of pyrolyzable defect groups, which create highly strained bonds upon their elimination.
