Analyses of C\(_2\)N material using mercury/potassium amalgam suspended in a 1:2 EtOH:HCl 2 M (v/v) solution. Optical microscopy at (a) normal light (in inset photography of large C\(_2\)N flake, scale bar = 300 \(\upmu \)m) and (b,c) polarized light at different relative angles showing large, thin, folded and crystalline flakes. (d) TEM image showing large, thin, layered (in inset) and homogeneous flakes. XPS analyses with spectra of (e) nitrogen, (f) carbon and potassium and (g) evolution of Hg at the same place as a function of time.
