“…Abdulkareem et.al reported that the CdO NPs modi ed using crocus plant extract with cadmium acetate as a precursor. Obtained NPs inhibit the growth of Staphylococcus aureus and Escherichia coli[29]. Saghatforoush et.al reported that Cd(OH) 2 was prepared by the solvothermal method, using cadmium chloride as source material.…”

This research work implies the development of a reliable, inexpensive, better and eco-friendly way to fabricate Cd(OH) 2 and CdO nanoparticles green synthesis approach using three different source materials. The veldt grape leaf act as a chelating agent. The physical properties of prepared samples were analyzed by various characterization techniques such as X-Ray Diffractometer, Fourier Transform Infra-Red, Scanning Electron Microscopy, X-Ray Energy Dispersive Spectrometer, High-Resolution Transmission Electron Microscopy and UV-Visible Spectrometer. The investigation of the structural analysis showed the existence of Cd(OH) 2 , mixed Cd(OH) 2 /CdO and CdO nanoparticles. The optical absorption wavelength at 294nm in UV-Vis spectra con rmed that the reduction of Cd 2+ ions. FTIR spectra display the vibrational modes of veldt grape leaf extract involved in chemical bonding and reductions. From EDAX spectrum con rmed the presence of Cd and O elements in the prepared samples. SEM and HRTEM images revealed nanorods, platelet and spherical shape morphologies with particle size ranging from 5.7 to 29nm. The photocatalytic activity of prepared nanoparticles was tested by degrading anionic and cationic dyes like congo red, methyl orange and crystal violet under UV-light irradiation. As well as antimicrobial activity was evaluated against gram-positive staphylococcus aureus, gram-negative proteus vulgaris and fungal-aspergillus niger. Comparing these three products CdO NPs exhibit high performance on both microbial and photocatalytic activity without a secondary product. Thus, the prepared CdO nanoparticles may further use in sewage treatment and biomedical applications.

“…It dissolves readily in acids but does not dissolve in alkalis. [37][38][39] In this work, we are going to investigate the electronic and optical properties (absorption, reflectivity, and dielectric function) of different zigzag SWCNTs at notations (4, 0), (5, 0) and (6, 0) for undoped and Cd-doped CNTs using the first principal method Cambridge Serial Total Energy Package (CASTEP) code.…”

Effects of doping cadmium atoms on the electronic and optical properties of (n, 0) zigzag single-wall carbon nanotubes SWCNTs are investigated by density functional theory DFT, using ultrasoft pseudopotential generalized gradient approximation GGA approach. The electronic and optical properties of the zigzag SWCNTs are susceptible and dependent on the n index and diameter of the tube; these features have only in nanotubes. Adding any impurity to the Zigzag SWCNTs must be caused to change in properties. The density of states for Cd-doped and un-doped SWCNTs increases with an increase in n index because of overlap valence and conduction bands in all situations (small bandgap). All samples have metallic characteristics. Almost all absorption and reflectivity spectra peaks are produced in the UV range. It can be noted that the peaks of the un-doped samples are higher than that of Cd-doped. Consequently, the material’s ability to store energy and photon absorption for un-doped nanotubes is larger than Cd-doped zigzag SWCNTs. These results are achieved in the figures of dielectric functions.
