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
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(+ ...
1. The ordered arrangement of carbon channels in the CMK-3 gave rise to the small-angle XRD peaks with two theta at 1.1°, 1.8° and 2.1° (Fig. 1a), which can be assigned to (1 0 0), (1 1 0) and (2 0 0) diffractions of two dimensional (2-D) hexagonal space group (p...
The present study examined the anticancer capabilities of Bacillus coagulans supernatant-produced copper oxide nanoparticles (BC-CuONPs) on MCF-7 and SKBR3 cancer cells. The X-ray diffraction, ultraviolet–visible spectroscopy, Fourier-transform infrared
sp.cell extract showed well-defined peaks at 2θ value that indicated their crystalline nature (Fig.1c). When the crystalline size decreases from bulk to nanoscale dimensions, the XRD peaks broaden19. XRD result showed that CuONPs formed are crystalline in nature with average size 22.5 nm clos...
Similarly, the peaks of Cu 2p3/2 and Cu 2p1/2 (Fig. S4) were observed at 932.0/934.6 and 951.8/954.5 eV, respectively, demonstrating that the presence of Cu2+ species in CuII-HHTP. Nearly the same XRD pattern of two catalysts indicated that CuIII-HHTP retained the same crystalline ...
Herein, we report the facile synthesis of multifunctional copper oxide nanosheets (CuO NS) using an aqueous extract of Rhazya stricta. The phytochemical investigation of R. stricta indicated the presence of saponins, tannins, and reducing sugars, responsible for the reduction and stabilization of CuO...
The structural and the optical properties of the glass have been measured by means of their XRD, FTIR, PL and UV-VIS spectra. From the results, the current sample shows a nonlinear optical property by emitting two prominent peaks at 504 and 540 nm (green light emission) under the ...
The α peaks with lower peak temperatures as compared to those of β′ and γ′ peaks have been attributed to the reduction of interface-boundary copper oxide species that contact closely and interact strongly with the supported ceria or YDC. Crystal sizes calculated from XRD measurements confirmed...
The copper oxide nanoparticles synthesized using Rhatany root extract involves preparing the Rhatany root extract by adding powdered Rhatany roots to boiling water, allowing the mix
