Abstract
Electrochemical water splitting is considered to be an environmentally friendly and efficient method of hydrogen production. NiFe LDH is a well-known electrocatalyst for oxygen evolution, yet its effectiveness in HER has been suboptimal. In this research, we created a Mo-NiFe LDH@NiS catalyst on carbon cloth via cation doping and heterointerface construction of NiFe LDH. The resulting Mo-NiFe LDH@NiS/CC showed remarkable HER activity. Furthermore, when used as a bifunctional electrode for overall water splitting, Mo-NiFe LDH@NiS/CC operated at a cell voltage of 1.58V at a current density of 10mA/cm² and exhibited outstanding durability. This study emphasizes the significant enhancement in HER and overall water-splitting efficiency of NiFe LDH achieved through Mo doping and heterostructure engineering, advancing its potential for effective water splitting applications.
