纳米NiCo2O4的制备及其电化学性能
Synthesis and Electrochemical Performance of NiCo2O4Nanoparticles
摘要
Abstract
NiCo2O4 nanoparticles with different morphologies were preparedvia microwave homogeneous precipitation using chloride and sulfate of nickel and cobalt as raw materials and urea as a precipitant. The results show that the resultant NiCo2O4 particles present a spinal structure after the calcination of the precursors synthesized with different mother salts. The resultant particles prepared with chloride show a thorn-ball shape assembled from needle-like nano-monomer, and exhibit specific capacitances of 150.7 F/g at scanning rate of 10 mV/s, and 107.3 F/g at scanning rate of 50 mV/s, respectively. The particles prepared with sulfate show a ball-flower shape assembled from nano-flake, and exhibit specific capacitances of 52.5 F/g at a scanning rate of 10 mV/s, and 39.7 F/g at a scanning rate of 50 mV/s, respectively.关键词
