SEM images of the product from 4-h electrolysis conducted at 790 °C and J = 0.6 A/cm2 with a stainless steel 304 anode at a 120 cm2 area brass cathode. AC TEM with 20 nm (A & C) and 10 nm (B) scale (3.5 to 7 million × magnification) showing the distinctive hemispherical concentric graphene layers surrounding the nucleation catalyst (C) and the concentric graphene adjacent layers above and below the hollow core (B, C). SEM magnification is D 1000×, E 5000×, F, G 6200×, H 20,000×, or I 110,000× magnification.
