Summary, etc. <p>Reduced Graphene Oxide (rGO) impregnated on alkaline earth oxides (Group 2) (CaO, SrO, BaO) matrix following mechanical mixing, thermal annealing and subsequent cold shock has synthesized a new electrochemical material. The characterization has been carried out by Fourier Transformation Infrared (FTIR) Spectroscopy, Scanning Electron Microscopy (SEM) and Powder X-Ray Diffraction (PXRD) measurements in µm dimension. Thermal stability has been checked by Thermal Gravimetric Analysis and Differential Scanning Calorimetry (TGA-DSC). Cyclic Voltammetry (CV) of the composites show anodic peak potential (E<sub>pa</sub>) order rGO-CaO (-0.6 V) &lt; rGO-SrO (-0.4 V) &lt; rGO-BaO (-0.3 V) which also follows ordering of ionic size, Ca<sup>2+ </sup>(100 pm)<sup> </sup>&lt; Sr<sup>2+</sup> (118 pm) &lt; Ba<sup>2+</sup> (135 pm). This character becomes more prominent as we move down the Group 2. Thermal stability of these coupled systems also increases down the group.</p>
