Design and Construction of Cu(OH)(2)/Ni(3)S(2) Composite Electrode on Cu Foam by Two-Step Electrodeposition

A Cu(OH)(2)/Ni(3)S(2) composite has been designed and in situ constructed on Cu foam substrate by facile two-step electrodeposition. Cu(OH)(2) is achieved on Cu foam by galvanostatic electrodeposition, and the subsequent coating of Ni(3)S(2) is realized by cyclic voltammetric (CV) electrodeposition....

Descripción
Sumario:A Cu(OH)(2)/Ni(3)S(2) composite has been designed and in situ constructed on Cu foam substrate by facile two-step electrodeposition. Cu(OH)(2) is achieved on Cu foam by galvanostatic electrodeposition, and the subsequent coating of Ni(3)S(2) is realized by cyclic voltammetric (CV) electrodeposition. The introduction of Cu(OH)(2) provides skeleton support and a large specific surface area for the Ni(3)S(2) electrodeposition. Benefiting from the selection of different components and preparation technology, the Cu(OH)(2)/Ni(3)S(2) composite exhibits enhanced electrochemical properties with a high specific capacitance of 4.85 F cm(−2) at 2 mA cm(−2) and long-term cyclic stability at 80.84% (4000 cycles).
