Cd(OH)2 and CdO: structural, optical, electron density distribution analysis with antibacterial assay

The present work is a systematic study on Cd(OH) 2 and CdO nanoparticle synthesized by hydrothermal route. The structural properties are confirmed with standard XRD results of Cd(OH) 2 and CdO. Phase transformation: Cd(OH) 2 (hexagonal) to CdO (face-centred) is a notable feature observed from the st...

Description
Summary:The present work is a systematic study on Cd(OH) 2 and CdO nanoparticle synthesized by hydrothermal route. The structural properties are confirmed with standard XRD results of Cd(OH) 2 and CdO. Phase transformation: Cd(OH) 2 (hexagonal) to CdO (face-centred) is a notable feature observed from the structural parameters. Further, Fourier transform infrared (FTIR), scanning electron microscope (SEM), UV–visible absorption and antibacterial studies were taken for Cd(OH) 2 and CdO. The FTIR spectra of Cd(OH) 2 show bands of 1404, 850 cm −1 which can be ascribed to the confirmation of Cd–O and 524 cm −1 assigned to Cd–O stretching in the spectra of CdO which correlates with the literature. The morphology of the both the samples shows the shape of nanocubes. Calcination of 400 °C is reflected in the reduced size of the particle in SEM. The optical bandgap of CdO (2.14 eV) is lower than Cd(OH) 2 (3.14 eV). The antibacterial evaluation shows that the effect observed was more in CdO than in Cd(OH) 2 . It was evident that the preparation time of CdONps was economical owing to its simplicity. Graphic abstract
