Abstract 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.

溶液吹塑法获得的 Ca 3 Co 4 O 9 纳米纤维的电化学评估

摘要 Ca3Co4O9 (C349) 纳米纤维是通过溶液吹塑纺丝 (SBS) 获得的，并被评估为氧还原和氧析出反应 (ORR 和 OER) 的电催化剂。煅烧纳米纤维的特征在于结构、形态和电化学特征。结果表明，C349 纳米纤维对 ORR/OER 的催化活性与碳相关材料的文献数据一致。面积电容比 TiO2 纳米管好得多。
