Ti3C2Tx composite Ni/Co nanofilm as highly efficient electrocatalyst for the hydrogen evolution reaction
In recent years, the demand for clean and sustainable hydrogen energy production via water electrolysis is significantly increasing. In this study, an efficient and stable Ti3C2Tx@Co Ni composite was synthesized using magnetron sputtering for hydrogen evolution reactions. The Ti3C2Tx@Co Ni composite exhibited excellent electrocatalytic activity and stability in alkaline conditions. Notably, it demonstrated the highest electrocatalytic performance in 1 M KOH, with the overpotential reduced to 142 mV at a current density of 10 mA·cm-2. After undergoing 24 h durability test, the Ti3C2Tx@Co Ni material demonstrated excellent stability. Importantly, a simple hydrogen evolution electrocatalysis mechanism is proposed. It is concluded that the incorporation of Co Ni metal and its interaction with single-layer Ti3C2Tx enhance the active sites and the charge transfer rate of the exposed metal. This research provides an innovative and practical strategy for the synthesis of nanostructures specifically designed for applications in electrocatalysis and energy storage.
