Summary
Herein, an efficient technique of getting ready CNT@NiM-OH nanocomposites by reacting dopamine-modified carbon nanotubes (CNT@PDA) with M(NO3)2 (M = Zn,Co) and 2-methylimidazole is reported. The analysis outcomes present that CNTs are intertwined to kind a community construction surrounded by NiM-OH in CNT@NiM-OH, which supplies a extra electrolyte contact space and response energetic websites. Electrochemical analysis signifies that CNT@NiM-OH displays glorious electrochemical properties for supercapacitors. The particular capacitances of CNT@NiCoZn-OH, CNT@NiZn-OH and CNT@NiCo-OH had been 2039.63, 1930.03 and 1664.73 F/g, respectively, at 1 A/g. As well as, the precise capacitance retention charges of the three electrode supplies after 1000 cycles had been 97.7%, 99.0% and 85.4%, respectively.
