Descripción
The aim of this paper was to describe the methods of nanocrystalline SnO2 preparation and to show the improvement of the behavior of a hydrogen sensor built with the grown SnO2 nanoparticles since particular properties of the nanomaterial are related to the sensor response. Nanocrystalline SnO2 was synthesized by gel-combustion and by reactive oxidation methods. Characterization was performed by X-Ray Diffraction (XRD), Brunauer-Emmer-Teller isotherms (BET) absorption and by High Resolution Transmission Electron Microscopy (HRTEM). A careful characterization enabled to control the crystallites size and properties to improve the behaviour of a hydrogen sensor. It was proved that if nanocrystalline SnO2 was used to build the resistive sensor, replacing the conventional microcrystalline SnO2, the sensor sensitivity increased between 30% and 35% (according to the grown crystallites size of nanocrystalline SnO2) and the working temperature (Tw) decreased from 350-450ºC to 180-220ºC. The Tw decrease obliged to improve the heating and measuring system of sensor which is also described.
