Monocrystalline Ni12P5 hollow spheres with ultrahigh specific surface areas as advanced electrocatalysts for the hydrogen evolution reaction†
Abstract
Monocrystalline Ni12P5 hollow spheres with ultrahigh specific surface areas were prepared by a water-in-oil microemulsion method. The novel structured Ni12P5 catalyst exhibited excellent catalytic activity and stability towards the hydrogen evolution reaction in acidic solutions.
