Fig. 3 a XPS spectra of S-doped GNCs before acid- treating and after vacuum-heating or air-oxidization removing doping structure, b XPS S2p spectra of GNCs before and after removing doping structure S-doping structure of air-oxidized GNCs is completely removed and therefore their S2p spectra is not distinguished
