Carbonaceous-based metal-free catalysts are promising aspirants for effective electrocatalytic hydrogen generation. Herein, we synthesized mesoporous-activated carbon nanosheets (ELC) from biomass eucalyptus leaves through KOH activation. The microstructure, structural, and textural characteristics of the prepared materials were characterized by FE-SEM, Raman, XRD, BET measurements. high temperature (700 °C) KOH-activated ELC exhibited an interconnected nanosheet morphology with a large specific surface area (1436 m2/g) mesoporosity. ELC-700 catalyst excellent HER performance low overpotential (39 mV at 10 mA/cm2), durability, Trivial Tafel slope (36 mV/dec) in 0.5 M H2SO4 electrolyte. These findings indicate new approach developing biomass-derived electrocatalysts substantially efficient green production.
