Electrochemical characterizations.
Voltage profiles of (a) bare CNT and different Co3O4 catalysts loaded CNT: (b) Co3O4 nanocubes, (c) pseudo octahedral Co3O4, (d) {110} facets exposed Co3O4 nanosheets, (e) {112} facets exposed Co3O4 nanolaminars and (f) {111} facets exposed hexagonal Co3O4 nanoplatelets. Blue and red lines represent the first and second cycles, respectively. Current density is 200 mA g−1.
