Abstract

Monodisperse ZnFe₂O₄ nanospheres were succesuffully synthesized via a nonaqueous route in benzyl alcohol at low temperaure of 200 °C. It was found that the ZnFe₂O₄ is 7–16 nm in diameter with a large surface area of 87.40 m²/g. The gas sensor based on ZnFe₂O₄ nanospheres shows a high pontential for detecting low-ppm-level toluene, exhibiting a good linearity ranging from 1 to 100 ppm with a high response (100 ppm:9.98) and excellent selectivity.
