From: Reducing and Uniforming the Co3 O 4 Particle Size by Sulfonated Graphenal Polymers for Electrochemical Applications

Fig. 2

ac SEM and TEM images showing that the Co3O4 particles were 50–200 nm sized and the interplanar distance of 0.233 nm corresponded to the stacking of (311) planes. df SGP reduced the particle size down to sub-20 nm, while the similar (311) stacking was observed with an interplanar distance of 0.244 nm. g, h XRD patterns and N2 adsorption-desorption isotherms for the Co3O4 and Co3O4/SGP powders
