Gas Adsorption Mechanisms on Tailored Hybrids

Gas sensing with carbon nanostructured materials has attracted a lot of interest and particularly single-walled carbon nanotubes (SWCNTs) have enormous potential for applications due to their unique structural and physical properties, such as large surface area to volume ratio and conductivity. However, the development of the next generation gas sensors stringent requirements, such as high sensitivity, high selectivity, fast response and optimal recovery, are imposed. SWCNTs have already been tested in those directions but not always the purity of the materials has been well controlled. This is the reason why many nanotube-based sensors have shown accuracy and durability problems that remain unsolved.
