Abstract
A kind of MoS2@CoFe-MOF electrocatalyst was prepared on carbon cloth by a one-pot hydrothermal method. Excellent electrocatalytic activity of MoS2@CoFe-MOF is demonstrated, and the catalyst has overpotentials of 220 mV and 405 mV at 10 mA cm−2 and 50 mA cm−2, respectively. It is found that the MoS2@CoFe-MOF electrode exhibits excellent stability at the end of operation for 48 000 s, and it has the highest electrochemically active specific surface area and the lowest charge transfer resistance. This work proposes a promising approach in energy chemistry for hydrogen production by electrolysis of water using electrocatalysts composed of non precious transition metal sulfides and bimetallic MOFs.
