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.
