Summary:Title screen
The development of low-cost, efficient, and sustainable electrocatalysts for hydrogen evolution reaction (HER) is crucial for advancing green hydrogen production. This study presents a novel vacuum-free electric arc synthesis of molybdenum carbide (Mo2C) using carbon derived from various biomass wastes (straw, willow leaves, leaf mixture, cedar chips, and rubber) as a sustainable carbon precursor. The optimal synthesis parameters were determined to be an arc discharge time of 120 s, a current of 100 A, and a 40% carbon excess, yielding nearly pure Mo2C powder with lattice parameters a – (4.749 ± 0.013) Å, b – (6.003 ± 0.012) Å, c – (5.234 ± 0.020) Å. Among the biomass sources, straw pyrolyzed at 600 °C provided the highest content of the Mo2C crystalline phase. The electrocatalytic performance of the synthesized materials was evaluated in both acidic and alkaline media. The Mo2C derived from cedar chips exhibited the best HER activity in 0.5 M H2SO4, with an overpotential of 0.334 V at 10 mA cm−2 and a Tafel slope of 117 mV dec−1. The pure Mo2C catalysts showed moderate activity
