摘要：

Trirutile-type CuSb2O6 nanoparticles were synthesized by a simple and economical route, starting from copper nitrate, antimony chloride, ethylenediamine, and ethyl alcohol as solvent. The latter was evaporated by microwave radiation at 140 W. The precursor material was calcined at 200, 300, 400, 500, and 600 degrees C, and analyzed by powder XRD. The oxide phase was obtained at the last calcination step (600 degrees C), whose powders were analyzed by field-emission scanning electron (FE-SEM) and transmission electron (TEM) microscopies. Microrods, hexagonal microplates, and nanoparticles with an average size of similar to 51.2 nm were observed. A forbidden bandwidth of 3.41 eV was detected for the direct transition with UV-vis. Tests were carried out on pellets made of the powders in carbon monoxide (CO) and propane (C3H8) atmospheres at different concentrations and operating temperatures, obtaining high response at 300 ppm of CO and 500 ppm of C3H8, both at 300 degrees C.
