<i>Psidium guajava</i> mediated green synthesized cobalt oxide nanoparticles dispersed on reduced graphene oxide for electrocatalytic water splitting.

ABSTRACT: In this research, we synthesized (Co₃O₄)_aq and (Co₃O₄)_et nanoparticles (NPs) utilizing aqueous and ethanolic extracts, respectively, of Psidium guajava leaves. The biosynthesized NPs were sonicated with reduced graphene oxide (rGO) to produce rGO@(CO₃O₄)_aq and rGO@(Co₃O₄)_et nanocomposites (NCs) and their respective calcined (700 °C) products rGO@(CO₃O₄)_aqc and rGO@(Co₃O₄)_etc. The nanomaterials (NMs) were characterized through XRD, FTIR, UV-visible spectroscopy, SEM, TGA, and DSC analyses. They exhibited crystallite sizes of 10-15.4 nm and band gaps of 5.1-5.9 mV. Their surfaces were coate
