Synthesis of Co₃O₄ Multilayer Nanosheet Material and its Promising Gas Sensing Property

Article Preview

Abstract:

Co₃O₄ multilayer nanosheets were synthesized by a hydrothermal method and a post annealing treatment process. The effect of solution concentration and ratio on the morphology of Co₃O₄ precursor was studied. The crystalline structure, morphology and elemental composition of Co₃O₄ multilayer nanosheets were characterized by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy technologies. When exposed to reducing gas such as ethanol, resistance of Co₃O₄ multilayer nanosheet sensor increases quickly, demonstrating that the Co₃O₄ multilayer nanosheets are p-type conductivity. For 100 ppm alcohol at 240 °C, the sensor response is as high as 32, indicating that the powder of Co₃O₄ multilayer nanosheets is a very promising low-powder gas sensing material.
