N-doped CMK-3 was utilized to confine the growth of MoS2 with a small size and an amorphous structure to form MoS2@N-CMK-3 which shows good electrocatalytic activity toward HER in acids with a quite small Tafel slope of 32 mV﹞dec−1. And more importantly, compared to MoS2@CMK-3, its electrocatalytic stability has been greatly improved resulted from N-doping.
