Fig. 3: Synthesis and characterizations of Z-type GPG.
From: Van-der-Waals-forces-modulated graphene-P-phenyl-graphene carbon allotropes
a The massive production of GO-P-GO from graphene oxide ink; b The GPG formed by pyrolysis of GO-P-GO; c The optical image of GPG film; d side view of X-CT image for the GPG film and 3D pore-network of the GPG film; e TEM image of multi-layer graphene; f TEM image, g enlarged TEM image, and h HRTEM image of Z-type GPG; i enlarged HRTEM (first), QSTEM simulation (second), theoretical model (third, grey balls and sticks are the carbon atoms and C-C bonds in graphene plane; blue balls and sticks are the carbon atoms and C-C bonds in the p-phenyl group), and CHGDIFF images (fourth) of Z-type GPG; j Typical TEM image, k Raman spectrum and l corresponding G/G+ peaks for Z-type GPG.
