Abstract

The preparation, characterization and sensing properties of CNT composites with a thin metal oxide (MOx) surface layer is presented. Atomic layer deposition (ALD) was applied for the coating of the inner and outer CNTs walls with thin films of ZnO and SnO₂ of precisely controlled thicknesses. Differently treated CNTs with different degree of surface functionalization were used as support for the oxide films. The sensing properties of the obtained composite materials towards NO₂ were investigated and related to the morphological and microstructural characteristics of both the coating and support. SnO₂-based composites on CNTs treated at 700 °C show enhanced performance as sensors, making them suitable for practical applications.
