摘要

The hollow Co ₃O ₄ microspheres were prepared by a gas-liquid diffusion reaction in the presence of ionic liquid [Bmim][BF ₄] in combination with calcination at 300 °C. Their structures and morphologies were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectrometry, and X-ray photoelectron spectroscopy. The growth mechanism of hollow Co ₃O ₄ microspheres was proposed. The ethanol sensing properties were measured using a WS-30A gas sensor measurement system. The influence of working temperatures, ethanol concentrations, and specific surface areas of Co ₃O ₄ microspheres on the ethanol sensing properties was investigated. The hollow Co ₃O ₄ microspheres showed excellent sensitivity to ethanol vapor at a lower operating temperature.
