MoS2@CoFe-MOF catalysts by one-pot hydrothermal synthesis enhanced electron interaction between MoS2 nanoflower and bimetallic MOF for efficient oxygen evolution

Abstract

A kind of MoS2@CoFe-MOF electrocatalyst was prepared on carbon cloth by one-pot hydrothermal method. The excellent electrocatalysts activity of MoS2@CoFe-MOF are demonstrated. It can use the overpotential of 220 mV and 405 mV respectively to drive 10 mA cm-2 and 50 mA cm-2. It is indicated that the MoS2@CoFe-MOF electrode exhibits excellent stability at the end of 48000 s, and it has the highest electrochemical activity specific surface area and the lowest charge transfer resistance. This work proposes a promising approach for hydrogen production by electrolysis of water using electrocatalysts composed of non precious transition metal sulfides and bimetallic MOFs in energy chemistry.
