Analytical Techniques of Manufacturing Highly Effective MSO/rGO Nanocomposite for Future Energy Conversion Technologies

Developing highly effective nanomaterials for water-splitting process is beneficial for energy conversion devices. This research focuses on the fabrication of inexpensive and stable nanomaterial, i.e. MnSnO₃ deposited on reduced graphene oxide (rGO) using ultrasonication technique for oxygen evolution reaction (OER) electrochemical in basic media. Their morphology vibrational mode and structure were examined by Scanning Electron Microscope (SEM), Raman Spectroscopy and X-ray diffraction (XRD) analysis. The outcomes indicate that the manufactured composite displayed an exceptional Tafel value (34 mV dec⁻¹), minimal overpotential (173 mV) and notable durability of 40 h in a 1 M KOH electrolyte as compared to pure MnSnO₃ nanoparticles. Moreover, fabricated nanomaterial exhibited remarkably least impedance (R_ct) of 1.1 Ω and enhanced stability over 5000th cycle. The catalytic electrode demonstrates exceptional durability for the OER, suggesting it a viable substitute for future energy conversion technologies.
