The development of efficient catalysts for the hydrogen evolution reaction (HER) is of extreme
importance for future renewable energy systems. In this work, we report on the synthesis of a novel hybrid
electrode that boracic nanospheres grown on the top of some NiCo2O4 nanowires with nickel foam as the
baseboard(B-NiCo2O4/NF). Due to this unique structural features, the electrocatalyst has a good activity for
HER, which needs overpotential of 150 mV to afford the current density of 10 mA cm-2, the catalytic activity
is maintained for at least 18 h. This work provides a promising methodology for the designing and fabricating
highly efficient boracic catalysts for HER.
