“…The value that was discovered Cd(OH) 2 is signi cantly greater than the CdO owing to absence of de ciencies and the phase modi cation in hexagonal Cd(OH) 2 as well as cubic CdO. Our ndings are well agree with previous reported literatures [37,46,57]. Therefore, we may conclude that the different precursor with same experimental conditions dramatically alter the value of E g produced oxide nanostructures manufactured by a practical, scalable and cost-effective green synthesis method.…”

“…In sample Cd-3 highly intense diffraction peaks were observed. All the peaks imply the formation of pure CdO cubic phase with a face-centred structure also, the high intensity of the peak observed space group as an allusion in JCPDS card 75-0591 and the peak pronounced asymmetry with different 'd' values [37]. The Sharp peaks denote the high crystallinity of the prepared sample Cd-3.…”

“…Therefore, peaks at 616-619 cm − 1 , 791 cm − 1 and 814 cm − 1 are indicating the presence of Cd-O and Cd-OH NPs in prepared samples [48]. The peaks became Sharp or broad it representing their phases, not crystallinity [37]. The hydroxyl group peak shifting 3517 cm − 1 to 3427 cm − 1 in the sample Cd-3, this suggest that the phenols and alcohol of leaves extract containing hydroxyl groups are used more in the reduction mechanism of cd 2+ .…”

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.

This study introduces an innovative method for synthesizing Cadmium Oxide /Cadmium Sulfide/Zinc Oxide heterostructures (CdO/CdS/ZnO), emphasizing their potential application in solar energy. Utilizing a combination of electrochemical deposition and oxygen annealing, the research provides a thorough analysis of the heterostructures through scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Raman spectroscopy, and photoluminescence (PL) spectroscopy. The findings reveal a complex surface morphology and a composite structure with significant contributions from hexagonal CdS and cubic CdO phases. The study highlights the uniformity in the distribution of luminescent centers and the crystalline quality of the heterostructures, which is evident from the PL analysis. The redshift observed in the emission peak and the additional peaks in the excitation spectrum indicate intricate optical properties influenced by various factors, including quantum confinement and lattice strain. The research demonstrates these heterostructures’ potential in enhancing solar cells’ efficiency and applicability in optoelectronic devices. This comprehensive characterization and analysis pave the way for future optimization and application in efficient and sustainable solar energy solutions.
