2017年10月19日 · In summary, CuS nanorod and nanoflakes were successfully synthesized by the hydro/solvothermal method. The XRD patters revealed the hexagonal structure of the CuS samples with high purity and crystallinity. The molecular structure of Cu S bond was identified by the FT-IR studies. The HR-SEM revealed the rod and flake shaped morphology for the ...

2016年9月1日 · SEM images show the morphology of the CuS nanostructures. Optical analyses were done by UV–visible and Fourier Transform Infra-Red Spectroscopy (FTIR) techniques. The band gap was calculated by Tauc relation and came out to be 2.89 eV. Copper sulphides with the formula Cux S y describe a family of chemical compounds and minerals.

In this work, we have synthesized the CuS/Cu (OH)2 nanocomposite electrode materials by the simple solvothermal method. The crystal structure, phase purity and the presence of functional groups...

Fourier transform infrared spectroscopy (FTIR) confirmed the formation of synthesized nanocomposites and the structural characteristics of synthesized nanoparticles were...

Fourier transform infrared spectroscopy (FTIR) spectra of the CuS/C-120 nanoparticles. In this study, the dense cloud-like structured CuS nanoparticles were...

Figure 3: FT-IR spectra for CuSnanoparticles. Figure 3 shows the FTIR spectrum of pure CuS nanoparticles. For pure CuS the major absorption at 1119.2 cm-1 is due to asymmetric S-O stretching of the sulfate species and 600 cm-1 and 456 cm-1 are due to consequence of the disulfides stretch (S-S).

Ultrasmall starch-capped CuS quantum dots (QDs) with controllable size were chemically fabricated in an aqueous medium. The phase of the CuS QDs was confirmed via X-ray diffraction (XRD), whereas the characteristic localized surface plasmon resonance (LSPR) peak in the near-infrared (NIR) region was measured using UV-Vis spectroscopy ...

Fourier transform infrared (FTIR) spectroscopy, 11 as a powerful nondestructive label-free fingerprinting tool measuring infrared light absorbed by molecules through the transient dipole moment change, has successfully attracted a lot of attention in analysis of biochemical materials, 12–14 including conformational changes of proteins, 15,16 ...
