Trirutile-type semiconductors have become alternative materials for the
detection of different types of gases, particularly CO, and C 3 H 8 . These materials
have gained in popularity because it is thought that their nanometric size is one
of the main reasons for their good performance in detecting gases. Such
semiconductor materials have been usually prepared by the ceramic method,
although other alternative routes have been also employed for the same
purpose. In this work, MnSb 2 O 6 nanoparticles synthesized by the colloidal
method (using antimony chloride, copper nitrate, ethylenediamine, and alcohol
as reagents) were tested as sensors in propane and carbon monoxide
atmospheres. The oxide MnSb 2 O 6 showed a hexagonal crystal structure (spatial
group P321 (150)) and morphologies like microcubes, microplates, nanorods,
and nanoparticles, with sizes of ~40 nm. The oxide also showed good thermal
stability and high sensitivity to both C 3 H 8 and CO. As the temperature and the
propane and carbon monoxide concentrations increased, the magnitude of
sensitivity also rose. The highest sensitivity was of ~ 0.439 for 500 ppm of C 3 H 8
at 300 °C, and ~ 8.98 for 300 ppm of CO at 300 °C. According to our results, the
MnSb 2 O 6 can be regarded as a good choice for sensing propane and carbon
monoxide.
