Abstract

Abstract: A promising mesoporous cobalt iron oxide (CoFe2O4) electrode material for supercapacitors has been synthesized via a chemical co-precipitation method using aluminum nitrate (Al(NO3)3) as a precursor of aluminum oxide (Al2O3) hard template. The as-prepared CoFe2O4 materials were spherical-like nanoparticles with diameter of around 25nm. Moreover, the as-prepared CoFe2O4 materials exhibited a high specific surface area (140.6m2 g−1) and high porosity (0.23cm3 g−1). The fabricated CoFe2O4 electrode showed typical pseudocapacitive behavior with a broad potential window (1.5V), a high specific capacitance (142Fg−1, 2mVs−1) and a long cycling life (71.8% retention after 1000 cycles).
