| Carbon nanotubes are a focus of intense study because of their unique physical and chemical properties. One of the most intriguing properties of carbon nanotubes is their electrical conductivity which can be highly sensitive to the presence of functional groups and adsorbed species. This finding has driven researchers to focus on understanding the surface chemistry of carbon nanotubes with small molecules for the development of nanoscale chemical sensors. To further this understanding, the reaction of carbon nanotubes with NO2 will be investigated at high and low pressures using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Possible reaction products and trapped or adsorbed species will be identified by their absorption frequencies while reaction rates will be determined by monitoring product growth as a function of time. This information together with estimates of product binding energies will be used to develop a mechanism for the NO2-nanotube reaction. |
