“…The calculated bandgap values for the hybrid structure of g-C 3 N 4 /ZnO and g-C 3 N 4 /CdO were found to be 2.97 eV and 2.30 eV, respectively. The earlier reported bandgap values of pure ZnO and CdO are 3.37 eV, 3.08 eV, respectively [42,43]. The effective interaction of graphitic carbon nitrides with ZnO and CdO is responsible for the altered bandgap values of metal oxide-graphitic carbon nitrides hybrid as compared to pure.…”

The study aims to evaluate the third-order optical nonlinearity caused by laser irradiation in transition metal oxide incorporated into graphitic carbon nitrides. The work describes the synthesis of nano-sized hybrid g-C3N4/ZnO (14%) and g-C3N4/CdO (14%). Nano-sized transition metal oxides: ZnO and CdO, have been prepared by thermally decomposing the organic precursors; Zinc Acetate Dihydrate, Cadmium Acetate Dihydrate, and Urea at 873 K. Graphitic carbon nitrides are synthesized from urea, which also functions as a reducing agent. The synthesized sample's structural and morphological characterization are investigated using X-ray diffraction (XRD), Fourier transforms infrared (FTIR), UV-Vis. spectra, field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDX). The grain size of the ZnO and CdO nanoparticles is observed to be ̴ 21 nm and ̴ 28 nm, respectively. The absorption in the samples is found to be 250-450 nm and transmit the light in the visible spectrum as observed in UV-Vis. spectra. The bandgap values calculated from Tauc’s plot for the hybrid structure of g-C3N4/ZnO and g-C3N4/CdO are found to be 2.97 eV and 2.30 eV. The z-scan method is adopted to evaluate the nonlinear susceptibility (χ3), intensity-dependent absorption coefficient (β), and nonlinear index of refraction (n2) using a pulsed Nd-YAG laser (~ 532 nm). The results of the composite of g-C3N4/ZnO and g-C3N4/CdO show good third-order susceptibility and hence are useful for use as an optical limiter.

“…Cadmium oxide has a wide range of applications like the manufacture of paint pigments and cadmium-coated baths. Cadmium oxide has many applications due to its high optical transparency and low ohmic resistivity [15][16][17]. 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 (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.

The coordination modes of the ligand observed in these complexes are shown in Scheme 1.The crystal structures of ketoacidoximate complexes are still unknown for many metals, and a rich structural chemistry can be expected due to the availability of multiple donor sites in the ligand. Herein, we report the synthesis and characterization of five ketoacidoximate complexes of cadmium (II), lead (II), and indium (III) and the CdO, PbO and In 2 O 3 particles formed by their thermal decomposition.
