Abstract: Peony-like submicrometer cupric oxide particles were synthesized by the water bath heating method using copper nitrate as copper source and methenamine as alkali source. The size and morphology of the as-prepared products were characterized by scanning electron microscopy. The gas sensing property of the product were measured by the stationary state gas distribution method. The results indicate that the cupric oxide particles are composed of microstructured triangular nanosheets. The morphology of the cupric oxide particles alters from spindle-like, via butterfly-like, to peony-like microstructure as the concentration of methenamine increases. The cupric oxide particles have better response to hydrogen sulfide.
Keywords: cupric oxide; microstructure; shape control; gas-sensing property
