Abstract
The advancement of highly active electrocatalysts holds significant importance in enhancing hydrogen production technology and fostering the growth of the hydrogen energy economy. Herein, we present a novel electrocatalyst, Cu-doped Co decorated Nitrogen-doped Ti 3C 2T x MXene Nanosheets (Cu/Co.TiO 2@N-Ti 3C 2T x), synthesized through a multi-step process involving the growth of Cu/Co-ZIF rhombic dodecahedrons on exfoliated Ti 3C 2T x MXene nanosheets, followed by heat treatment. The resulting electrocatalyst exhibited remarkable performance in hydrogen evolution, with a low overpotential of 78 mV at − 10 mA/cm 2 in a 1.0 M KOH solution. Tafel slope analysis revealed rapid kinetic response (119 mV dec −1), and the electrocatalyst demonstrated exceptional durability over a 24-hour Chronopotential run. This outstanding performance can be attributed to the synergistic effects of N-Ti 3C 2T x nanosheets, Cu/Co, and TiO 2, providing excellent electronic conductivity and structural robustness. Overall, the Cu/Co.TiO 2@N-Ti 3C 2T x composite offers significant potential for advancing hydrogen production technology, contributing to carbon emission reduction and environmental protection.
