我们成功开发了基于MOF（Co3[Fe(CN)6]2·10H2O）的策略来合成Co-Fe混合金属氧化物（Co3O4/Fe2O3）纳米立方体（记为CFNC）。所得CFNC可用作高性能对称超级电容器的阳极和阴极，在1125Wkg−1的功率密度下表现出35.15Whkg−1的高能量密度以及优异的稳定性。同时，当CFNC用作析氧反应（OER）电催化剂时，需要310mV的低过电位即可实现10mAcm−2的电流密度，并表现出优异的稳定性。
We have successfully developed a MOF-based (Co3[Fe(CN)6]2·10H2O) strategy to synthesize Co-Fe mixed metal oxide (Co3O4/Fe2O3) nanocubes (denoted as CFNC). The obtained CFNC is applied as both anode and cathode for high-performance symmetric supercapacitors, exhibiting high energy density of 35.15 W h kg−1at a power density of 1125 W kg−1as well as excellent stability. Meanwhile, when CFNC is used as electrocatalyst for oxygen evolution reaction (OER), it requires a low overpotential of 310 mV to achieve a current density of 10 mA cm−2and exhibited excellent stability.
