Co-entrapped, N-doped porous carbon (CoNPC) was synthesized via combination of hand milling and carbonation. Glucose and melamine were used as the carbon precursor and nitrogen precursor, respectively. ZnCl2 was utilized as the template, which could be removed totally with water. CoNPC possess a high BET surface area of 728.4 m(2) g (-1). The obtained catalyst exhibits excellent performance for hydrogen evolution reaction in both acidic and basic media, achieving a current density of 10 mA cm(-2) at 171 and 202 mV in acid and base, respectively.
