Controllable Construction of IrCo Nanoclusters and the Performance for Water Electrolysis
Finding a suitable catalyst is an important research direction in hydrogen (H<sub>2</sub>) production from water electrolysis. We report a synthetic method to obtain Ir<sub>x</sub>Co/C clusters by polyol reduction. The catalyst is small in size and can be evenly distributed....

| description | Finding a suitable catalyst is an important research direction in hydrogen (H<sub>2</sub>) production from water electrolysis. We report a synthetic method to obtain Ir<sub>x</sub>Co/C clusters by polyol reduction. The catalyst is small in size and can be evenly distributed. The Ir<sub>3</sub>Co/C cluster catalyst had very good activity under acidic conditions. The overpotential of the best-performing Ir<sub>3</sub>Co/C cluster for the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) is only 290 mV and 91 mV when 10 mA cm<sup>−2</sup> and 100 mA cm<sup>−2</sup>. The catalyst performance may be improved because of the synergistic effect and the small size of the prepared catalyst, which accelerates proton transfer. This approach offers a strategy to reduce costs while improving catalytic activity. |
