Nickel/Porous Carbon Composite Derived from Bimetallic MOFs for Electrical Double-Layer Supercapacitor Application

Abstract

A novel method to synthesize nickel/ porous activated carbon composite materials has been proposed initially from bimetallic Ni(II)-MOF-5s. Electrochemical results present that the nickel /activated carbon maintains nearly 83 % capacity with the current density increases from 0.2 to 50 A g -1 and shows excellent cyclic stability of about 1.5 % decrease after 5000 cycles. This product also demonstrated a good rectangularity at a high scan voltage of 2 V s -1 and very low charge transfer resistance of approximately 0.35 Ω, which can be a prospective electrode material for electrochemical double-layer supercapacitor applications.

“…Dong et al [20] developed interconnected porous carbon nanosheet/nickel foam composite for high-performance supercapacitors by microwave-assisted heating. Meng et al [21] studied a nickel/porous carbon composite for electrical double-layer supercapacitor application. Zhang et al [22] used porous nickel-based metal organic framework/carbon nanotubes composite as the glucose sensor base.…”
