Current research involved fabrication of cadmium oxide-graphitic carbon nitride (CdO/g-C3N4) nanocomposite and evaluation of their photocatalytic properties by physical and electrochemical analysis techniques. The X-ray diffraction (XRD) test demonstrated that the nanocomposite consists of graphite and monteponite phases. UV–Vis absorption and photoluminescence (PL) analysis clearly pointed out both the band gap reduction and inhibition in recombination rate of charge carriers. Based on the photoelectrochemical (PEC) analysis, linear sweep voltammetry (LSV) data demonstrated that CdO/g-C3N4 nanocomposite shows higher anodic current (0.57 mA/cm2) under light emission as compared to dark environment (0.02 mA/cm2). This study was also deliberated with proposed mechanism on photoreforming of wastewater reaction scheme.

Palm oil based alkyd resin was prepared by alcoholysis–polyesterification reaction over hetero-homo catalytic system comprised of CuO nanoparticle and NaOH. In this work, CuO nano-sol was synthesized in glycerol at ambient condition via a chemical reduction method and successively used in alkyd resin preparation. The formation of CuO nanoparticle was monitored by X-ray absorption near edge structure spectroscopy (XANES) where a ‘red colour sol’ was detected. During the alkyd resin preparation, the catalytic behaviour of CuO nanoparticle was recorded by using titration method. The formation of the alkyd was confirmed by FTIR. The antibacterial behaviour of the additive was verified by Kirby–Bauer method and found that alkyd with CuO nanoparticle presented better antibacterial performance.
