Sensory properties of carbon nanotubes containing impurity boron atoms

Abstract

Nanotubes, being one of the most demanded nanotechnology materials, are finding new areas of application. One of these areas is their use as highly sensitive sensors. However, in the practical application of nanotubes, it often turns out that, despite the positive sorption properties, a change in their electronic state does not occur after the capture of the analyte. This fact significantly complicates the possibility of their use as sensory nanosensors. One of the ways to improve the electronic properties of carbon nanotubes by creating heterostructures on their surface is modification with various atoms. At the same time, one of the most effective substances for carrying out the substitution reaction is boron. It makes it possible to create a redistribution of electron density on the surface of nanotubes without introducing significant changes in the topology of the nanotube surface. This article analyzes a model experiment to study the possibility of using the nanotubes themselves as highly sensitive nanosensors in relation to carbon dioxide molecules.
