The structure, morphology and electrochemical performance of the obtained samples were systematically investigated by X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FT-IR), Raman spectra and so on. According to the TEM analysis, needlelike and...

With the ease of large scale fabrication and superior electrochemical characteristics, Co3O4/Ni(OH)2composite mesoporous NNs grown on Ti substrates will be good candidates for supercapacitor applications. 展开 关键词: Experimental/ cobalt compounds electrochemical electrodes Fourier transform spectra heat ...
Raman spectroscopy was used to study the mineral bottinoite and a comparison with the Raman spectra of brandholzite was made. An intense sharp Raman band at 618 cm−1 is attributed to the SbO symmetric stretching mode. The low intensity band at 735 cm−1 is ascribed to the SbO antisymm...
