A Comparative Study of Cerium- and Ytterbium-Based GO/g-C3N4/Fe2O3 Composites for Electrochemical and Photocatalytic Applications

The design of sustainable and efficient materials for energy storage degradation environmental pollutants (specifically organic dyes) is a matter major interest these days. For this purpose, cerium- ytterbium-based GO/g-C3N4/Fe2O3 composites have been synthesized to explore their properties, especially in charge devices such as supercapacitors, also photocatalysts the carcinogenic dyes from environment. Physicochemical studies carried out using XRD, FTIR, SEM, BET techniques. Electrochemical techniques (cyclic voltammetry, galvanic discharge, electrochemical impedance spectroscopy) employed measure super-capacitance EDLC properties. Results show that gravimetric capacitance calculated GCD results 219 Fg−1 ytterbium- 169 cerium-based nanocomposites at current density 1 A/g scan rate 2 mV/sec. specific nanocomposite 189 compared 125 material. EIS pointed an enhanced resistance offered by ytterbium, which can be assumed with difference particle size, confirmed structural including XRD. From obtained results, ytterbium oxide-based proven better electro-catalyst nanocomposites. Photocatalytic are agreement efficiency (67.11 83.50% rhodamine B methylene blue surpasses values observed (63.08 70.61%).
