Abstract
A design of efficient and robust electrocatalysts for hydrogen evolution reaction (HER) under all pH conditions is provided. Especially, the present invention provides a yolk-shell nanostructure with Rh nanoparticles embedded in S, N co-doped carbon nanostructures prepared by a facile self-template method. The obtained nanostructures can achieve an extremely small overpotential of 10-20 mV at 10 mA cm, a Tafel slope of 20-30 mV dec, a TOF of 0.1-0.3 s(at −75 mV/RHE) and long-term durability more than 10 hours.
