Abstract

Energy conversion and storage technologies are currently receiving a lot of attention because they offer solution for growing energy problems. The present work reported on the fabrication of CeMnO₃/GO nanocomposite through a hydrothermal method. Different analytical strategies have been employed for the physical and electrochemical analysis. The capacitance (C_s) values of prepared composite were 1106 F/g with specific energy (S_E) 62 Wh/Kg and specific power (S_P) 315 W/kg at current density 1 A/g which showed stability even after 3000th cycle for 50 h. The synthesized CeMnO₃/GO composite possessed overpotentials (η) of 213 mV and Tafel slope value of 36 mV/dec determined from CV analysis for water splitting studies. The addition of graphene oxide to CeMnO₃, improves interfacial area and facilitates faster charge transport which results improvement in electrochemical performance. The Nyquist plot examines smaller charge transfer resistance value of 0.87 Ω for CeMnO₃@GO nanocomposite. The material's remarkable stability suggested its potential for storing energy for supercapacitor applications.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
