Fig. 4 a Nitrogen adsorptiondesorption isotherms showing a much higher uptake of N 2 in doping-removed GNCs air-oxidized GNCs than S-doped GNCs Fig. 2c. b Mesopore size distributions BJH showing that there is a much higher population of mesopores in the air-oxidized GNCs than in other ones. c Raman spectra of GNCs before and after removing S-doping structure. d HRTEM image of the GNCs after removing S-doping structure nanopores are arrowed
