Electrocatalysts are of great importance for water splitting to produce hydrogen. Here, NiO and CrO3 double surface-decorate Ni (Ni@NiO@CrO3) nanofibers were prepared by electrospinning as highly effective and stable electrocatalysts for hydrogen evolution reaction. It shows high electrocatalytic activity (100mAcm−2 at a low overpotential versus RHE at 228mV) and superior stability (after 120h without...
