a N2 adsorption-desorption isotherms for the Co3O4 nanoparticles grown in the NaOH and NH3 solutions. b, c Comparisons in CV and GCD for different Co3O4 growths. d Specific capacitances at current densities ranging from 0.2 to 2 A/g. For a comprehensive comparison, the capacitances at 0.2 A/g for the free growth in different solutions were also plotted
