NiO空心微球的规模化制备与表征
Large scale preparation and characterization of NiO hollow microspheres
摘要
Abstract
First,the a-Ni(OH)_2 precursor precipitates were prepared by homogeneous precipitation method without hydrothermal treatment and presence of template.The method was carried out in the media of ethanol-water under the condition of constant temperature of 85 ℃ using NH_3·H_2O and Ni(NO_3)_2 as raw materials.And then the precipitates were calcined at 400 ℃ to obtain hollow microspheres self-assembled from NiO nanosheets.The microspheres were characterized by XRD and SEM.The results show that the NiO hollow microspheres are of hexagonal structure and the nanosheets are vertically arranged on the surface of spheric shell;the size of the nanosheet is about 2 μm×2 μm with the thickness less than 100 nm.The influence of ethanol on formation of the microsphere morphology was studied,and the self-assembled mechanism of NiO hollow microsphere was preliminary explored.关键词
