Growing of 2D/3D graphene structures on natural substrates …
In the second step, iron (Fe)-treated micron talc and Fe-treated fine talc were also utilized as substrates to observe the effect of surface activation of talc on graphene formation. Hereby, chemical activation of micron talc/fine talc was performed in a 0.5 M FeCl 3 aqueous solution (500 ml) through refluxing at 80 °C for 24 h. Then, the ...
