a UV‒Vis absorption spectra. The inset shows a photograph of the two samples. b EPR spectra in terms of the g-factor. c N K-edge NEXAFS spectra. d Structural model representation and solid-state 13C and 15N NMR spectra. e Phase hysteresis loop and amplitude butterfly loop of C3N5 and C3N4. f Surface potential from KPFM images of C3N4 and C3N5 with (w/) and without (w/o) light irradiation.
