Copper oxide (CuO) nanoparticles are prepared by the hydrothermal method which is used as a heterogeneous catalyst to synthesize 3-(2-chlorophenyl)-2,4-Pentadione. The energy band gap of HOMO-LUMO of CuO NPs is calculated using a UV-vis study which is found to be 1.96eV. The crystalline...
Photoelectrochemical water splitting is a promising solution for harnessing solar radiation for hydrogen production. Copper oxide semiconductors, particularly materials based on cuprous oxide, have attracted attention due to their abundant elemental avai
Unlike the separated components, copper-copper oxide heterostructural nanocrystals embedded on g-C3N4can promote photocatalytic activity. Furthermore, among other Cu-Cu2O/g-C3N4samples, the ternary one with 30% wt. Cu-Cu2O showed the best catalytic degradation efficiency, achieving a degradation rate ...
The higher calorific value of the copper oxide blended fuel aids in achieved peak pressure close to standard diesel [333]. HRR is higher for standard diesel than copper oxide blended biodiesel. However, addition of copper oxide is found to increase the HRR of the blend and increases with ...
The ratio of the sum of the areas of peaks 2, 3 and 4 to that of peak 1 was used as a measure of the relative amount of Cu(+ 2) to Cu(+ 1) on the surface. As the Cu oxide particle size increases, the relative amount of XPS induced reduction decreases. Intensity from Cu(+ ...
Herein, we reported the green synthesis of copper oxide nanoparticles (CuONPs) from Solanum tuberosum (potato) extracts to assist the photodegradation of methylene blue dye. SPR peaks indicated the formation of the nanoparticle at 273 nm (highest peak intensity) with 25-mM precursor salt and 10 ...
In order to investigate the dependence of full width at half maximum (FWHM) of XRD peak or the grain size on the film thickness, we further carried out XRD measurements for the as-grown CuI thin films with different thicknesses. The FWHM of the (111) diffraction peak is found to ...
In this research, a one step, facile route has been undertaken to synthesise copper oxide/reduced graphene oxide (CuO/rGO) nanocomposites. X-ray powder diffraction analysis (XRD) was carried out to identity the crystalline structure and phase of the synthesised sample. Elemental analysis and ...
the presence of Co ions in the sample is observed by a stretch at 690 cm−1on the FTIR spectrum. This peak corresponds to a specific vibration related to cobalt incorporation into the copper oxide lattice [42]. The Co-CuO HNCs's FTIR spectrum showed all of the characteristic peaks exhibi...
For copper oxide, the measured X-ray diffraction (XRD) data and the standard XRD data from the International Centre for Diffraction Data (ICDD) card (card no. DB 01-080-1917) were compared. The shape and size of the produced CuO NPs were examined using transmission electron microscopy (TEM...
