| description | A facile one-pot hydrothermal method has been demonstrated for the fabrication of an innovative hydrangea-like NiSe/FeSe2 nanocatalyst for boosting oxygen evolution reaction (OER). Benefitting from the advantages of the porous architecture, high specific surface area, facilitated electron transfer rate, an ultralow overpotential of merely 210 mV is required for the optimized NiSe/FeSe2(1:1.5) to drive the electrocatalytic water oxidation to reach to 10 mA cm−2. Moreover, by equipping NiSe/FeSe2(1:1.5) with Pt/C for electrochemical water splitting, a cell potential of merely 1.60 V is demanded to attain 10 mA cm−2, even outperforming the IrO2 ‖ Pt/C couple. More importantly, the structure and morphology of NiSe/FeSe2(1:1.5) are still well maintained after a long-term chronopotentiometry test. This work opens a new avenue for constructing effective and durable non-precious electrocatalysts for OER. |
