2012年1月15日 · Cupric oxide (CuO) nanoparticles with an average size of 6 nm have been successfully prepared by an alcothermal method. The prepared CuO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared (FT-IR) and UV–visible absorption spectroscopy.

We have synthesized CuO and Cu 2 O nanoparticles by sol-gel method for possible applications in photo-voltaic or energy storage devices. XRD pattern clearly indicates the formation of pure CuO...

FTIR spectrum of CuO shows peaks at 437.84, 516.92, and 590.22 cm −1 revealed the formation of CuO as shown in Figure 1 a. A broad peak noticed at 3433 cm −1 attributed to O-H stretching of...

Cu-O bond structure was identified in FTIR analysis. In XRD analysis, peaks defining CuO NPs were observed. The antioxidant and photocatalytic activity of the synthesized CuO NPs were...

2020年6月13日 · CuO nanoparticles were prepared by a simple and cheap method from thermal decomposition of new copper precursor at 500 ºC and 600 ºC. UV–Vis and optical data confirmed the surface plasmon resonance and FT-IR and XRD results confirmed the preparation of single phase of CuO nanoparticles.

2019年7月12日 · The FTIR spectrum of the sample annealed at 350 °C consists of three peaks at 432, 530 and 606 cm −1 can be assigned to the A u mode, B u mode, and the other B u mode of CuO, respectively. These FTIR peaks correspond to characteristic stretching vibrations of Cu(II)–O bond in the CuO phase [19], [45].

1987年12月1日 · The surface properties of CuO prepared by thermal decomposition of Cu (OH) 2 ·CuCO 3 have been studied by FT-IR spectroscopy of CO, CO 2, pyridine, pivalonitrile, methanol and formic acid adsorbed in the 200–420 K temperature range.

The crystalline structure of the synthesized CuO was determined by X ray diffractogram obtained on XPERT-PRO powder diffractometer with Cu-Kα radiation. The FTIR of the sample was taken in the region between 400-4000cm-1 on a Thermo-Nicolet Avatar 370 model FTIR. The UV-Visible absorption spectrum of CuO has been recorded by

2021年2月9日 · Among the FT-IR spectra, CuNa 2 (OH) 4 nanoparticle shows a strong broad absorption band from 2500 to 3750 cm −1 corresponds to hydroxyl (OH) functional groups presented in the compound.

2020年12月14日 · The synthesized CuO were confirmed by spectroscopic and morphological characterization such as ultraviolet-visible (UV-vis) spectroscopy, fourier transform infrared (FTIR) spectroscopy, zeta potential, scanning electron microscopy (SEM) and energy dispersed X …
