Copper oxide–ferric oxideNanocompositeTEMFTIRAntibacterialAntifungalRecently, copper oxide–ferric oxide nanocomposites (CuO/Fe2O3-NCs) have gained popularity and are widely employed in various applications. However, their effectiveness against phytopathogens has not been studied yet. This study investigates...
The FTIR spectra of: a ZnO and b CuO nanoparticles Full size image The absorption peaks at 3724 cm−1 and 3607 cm−1 were attributed to the O–H bending vibration, indicating the presence of a small amount of H2O in the ZnO NPs. The broad band at 3400 cm−1 and the peak at ...
The presence of different functional groups was confirmed through FTIR in the range of 4000–600 cm−1. The fabricated nanoparticles were further characterized by X-ray diffractometry to check their crystalline nature. Antibacterial susceptibility testing of biofabricated copper oxide nanoparticles The ...
The stretching vibrations of Cu(II)-O in CuO are responsible for the absorption bands observed in the FTIR spectra of MO-CuNPs at 408 cm−1, 447 cm−1, 470 cm−1, 555 cm−1, and 594 cm−1. The spectral bands at 1234 cm−1and 1064 cm−1correspond to the C-O stretchi...
This study focuses on the synthesis of zinc and copper oxide nanoparticles using green methods by plant extracts. The resulting metal oxides were analyzed using FT-IR spectroscopy, TGA, TEM, zeta potential and assessed for their efficacy as pigments based on properties such as Hydrogen Ion Concentr...
Figure 2.FTIR spectra of 30% Cu-Cu2O/g-C3N4. To further understand the element composition and chemical states in the Cu-Cu2O/g-C3N4, the X-ray photoelectron spectroscopy (XPS) tests of the 30% Cu-Cu2O/g-C3N4sample were conducted. As shown inFigure 3a, the XPS survey spectrum indicated...
Raman spectra indicated the presence of evident peak at 614 cm−1 represented the presence of copper oxide nanoparticles. On the other hand, authors also reported that the synthesized nanoparticle exhibited excellent antimicrobial activity against bacterial strains (Bacillus cereus and Pseudomonas ...
crystal structure: FTIR spectroscopy: quantumchemical calculationsDichlorobis(triphenylphosphineoxide)copper(II) has been prepared as a side product and a subunit of tetranuclear 4-oxo bridged complexes. The molecular structure, already known in the literature, was redetermined using X-ray diffraction ...
Fourier transformation infrared (FTIR) spectra of the KBr pellets were obtained using a JASCO FT/IR680 spectrophotometer to investigate the potential for chemical interaction between Cu and O of the CuO NPs. An energy-dispersive X-ray spectrometer built inside the gadget was utilized to employ ...
These FTIR spectral features are consistent with the XRD results, indicating the existence of g-C3N4 with a tri-s-triazine framework structure [37]. No copper oxide peaks existing in the spectra confirm the single-atom state of Cu in carbon nitride support. 3.2 Atomic structure analysis of ...
