Abstract

Cadmium oxide (CdO) nanomaterial has been synthesized by electrochemical method which is simple and inexpensive method. The synthesized cadmium oxide nanomaterial was used as a catalyst for the photocatalytic degradation of acetic acid, formic acid and oxalic acids under varies experimental conditions by volumetric method. The synthesized nanomaterials were characterized by various techniques such as UV-Visible spectroscopy, SEM-EDAX, FT-IR spectrum and X-ray diffraction studies. The UV-VIS spectroscopy study revealed that the band gap energy of cadmium oxide nanomaterials to be 2. 85 eV Tauc plot. The structure of cadmium oxide was found to be cubic structure and crystal size was found to be 32 nm which was confirmed from XRD data. SEM reports showed that the cadmium oxide nanomaterials have regular spherical shape and uniform size. The presence of cadmium and oxygen in the nanomaterial is confirmed from the EDAX spectrum. FT-IR spectra reveal the presence of characteristic band corresponds to Cd-O mode. The photocatalytic activity of the synthesized cadmium oxide nanomaterial was examined by the kinetics of photodegradation of carboxylic acids by volumetric method by using NaOH solution. Taft LFER was tested the isokinetic temperature β was calculated for oxidation of carboxylic acids. The antibacterial activity of cadmium oxide nanomaterial was investigated.<div><br></div>

Summary

Introduction

Nanoparticles have enchanted prestigious awareness due to their individual chemical and physical properties, which are dissimilar from those of either the bulk materials or single atoms. Nanoparticles are of great awareness for many technical applications in dependent physical properties like fundamental research [1,2,3,4]. Many scholars have focused on metal oxide due to their applications in several areas of research, peculiarly in optoelectronic and other applications, including phototransistors, solar cells, transparent electrodes, photodiodes and gas sensors [5,6]. Cadmium oxide (CdO) is one of the binary oxides having important electronic, structural, and optical properties. In recent years we observed that the metal oxide nanomaterials play a significant role in several areas of chemistry, materials science and physics. Cadmium oxide is one such material which takes over excellent optoelectronic and structural properties. The synthesized cadmium oxide nanomaterials on photodegradation of carboxylic acids by volumetric method by using NaOH solution and the kinetics of degradation of carboxylic acids were studied
