Ca3Co4O9 (C349) nanofibres were obtained by Solution Blow Spinning (SBS) and evaluated as electrocatalysts for Oxygen Reduction and Oxygen Evolution Reactions (ORR and OER). Calcined nanofibres were characterised in terms of structural, morphological and electrochemical features. Results showed that catalytic activity of C349 nanofibres for ORR/OER is in line with literature data for carbon-related materials. The areal capacitance is much better than that of TiO2 nanotubes.
