Abstract
This work targets the design of a novel composite nanomaterial (NCM) based on the exchange of electro current between magnesium oxide and yttrium oxide on the surface of the synthetic self-assembly (graphene oxide/carboxymethyl cellulose) for supercapacitors, biosensors, and photocatalytic. The different techniques utilize for the characteristic synthesized NCM such as morphology, optical properties, and structural evidence. The electrochemical behaviors and the optical properties perform emphasize the improvement of the electron transfer via the incorporation of the two metal oxides on the surface of the self-assemble. The photocatalytic efficiency records at 85% after 80 min, and the rate constant documents at 4 × 10−3 min−1 due to the ease of the oxygen reactive species generation for removing the pollutants. The impedance spectroscopy data emphasize the development of the surface and electron transfer that enable it to be a promising candidate for supercapacitors applications. The capacitance value of CNM has been documented at 58.81 nF/cm2, also the biosensor applications for glucose and D-galactose are detected by UV–Vis spectroscopy and the electrochemical method. From the results, the CNM is a promising candidate for water treatment membrane, supercapacitors manufacture, and biosensors applications.
