摘要：
Rose-like NiO structures were fabricated by calcining the solvothermally formed alpha-Ni(OH)(2) structure with similar morphology. The product was characterized by X-ray diffraction, transmission electron microscopy, scanning electron microscopy, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The rose-like alpha-Ni(OH)(2) nanostructure was an aggregation of nanoparticles with a size of ca. 3-4 nm. The decolorization of acid fuchsine solution was studied using prepared NiO as the catalyst and commercial P25 as the reference. The degradation products were analyzed by gas chromatography-mass spectrometry and ultraviolet-visible spectroscopy. The product exhibited much higher photocatalytic activity than P25.
