摘要

Abstract

The disordered arrangement and thereof inferior conductivity of 2D MOF sheets seriously hinder their practical application. Herein

we propose in situ transformation strategy to architect vertically oriented bimetallic CuNi-MOF as a self-supporting electrode

leading to a decuple high specific capacitance of 1262 C g

-1

in comparison with the pristine Ni-MOF powder of 114 C g

-1

at 2 A g

-1

. DFT calculations reveal that introduction of Cu can modulate the electronic structure of metal centers in the Ni-MOF sheets and optimize electrical conductivity. Our strategy is promising to maximize the utilization of MOF superiorities for optimizing their electrochemical performance.
