摘要
In this work, Ni3V2O8 particles were synthesized by a chemical method and sintered, and then, polypyrrole (PPy) films were deposited onto the surface of the Ni3V2O8 particles by in situ chemical polymerization. The morphology and structure of these materials were characterized. Morphological observation proved that the PPy film was well dispersed and completely coated onto the surface of the Ni3V2O8 particles. The Ni3V2O8 particles showed high response to volatile organic gases at 300 degrees C. The composite of Ni3V2O8/PPy exhibited high response to NH3 and NO at 150 degrees C, showing great potential for detecting these gases.
