Novel NiO flower-like microspheres with abundant nanoparticles adhering to the petals: Hydrothermal synthesis and their gas sensing properties

摘要: Abstract Nanomaterials with three-dimensional architectures, frequently exhibiting novel functional properties, have attracted considerable attention of the researchers. In current work, we successfully synthesized NiO flower-like microspheres abundant nanoparticles adhering to petals via a facile hydrothermal method. Interestingly, it is found that excellent gas sensing properties samples towards ethanol are likely attributed well-aligned porous architectures as well great amounts petals, considered active sites. Meanwhile, also elaborated distinctive growth mechanism such unique architecture and plausible mechanism, respectively.
