Water electrolysis, generating clean hydrogen, always requires high-performance and low-cost electrocatalysts. Ionic liquid, namely N,N-bis(4-(methoxycarbonyl)benzyl)-N-methyl-d-glucaminium hexaflorophosphate (MBMG-PF6), was infiltrated into the pretreated graphene as the precursor to prepare N,P-double doped graphene (G((PF6))). This material has been applied as a metal-free electrocatalyst for hydrogen evolution reaction (HER), demonstrating a good catalytic activity with an onset overpotential of 100mV, a Tafel slope of 88mV dec(-1), a 97% Faradaic efficiency (FE) and a good durability over 10h. According to the structural and compositional studies, this good HER performance can be attributed to the N,P-dopant and highly porous structure of this catalyst.
