Multicomponent N doped graphene coating Co@Zn heterostructures electrocatalysts as high efficiency HER electrocatalyst in alkaline electrolyte

Multicomponent N doped graphene (NG) coating [email protected] heterostructures ([email protected]@Zn) were successfully synthesized and used for hydrogen evolution reaction (HER). Benefit from high conductivity, high density of active sites, the multicomponent [email protected]@[email protected] catalyst exhibits an excellent HER performance, indicating its potential on hydrogen evolution as non-noble metal-based electrocatalyst. The multicomponent [email protected]@Zn heterostructures with more electron deficiency Co shows outperform HER activity owning to the accelerated electron transport between NG and [email protected] This work provide a novel strategy to design non-noble metal multicomponent HER electrocatalysts.
