Scanning electron microscopy (SEM) image and the Energy dispersive spectroscopy (EDS) elemental mapping of the (a) MEPCM, (b) Ni/MEPCM, and (c) Ni/α-Al2O3. In the elemental mapping, the red area represents O, the green area represents Al, the yellow area represents Si and the purple area represents Ni.
