摘要:
The present communication reports the topotactic conversion of NiCo<inf>2</inf>O<inf>4</inf>nanowires array on carbon cloth (NiCo<inf>2</inf>O<inf>4</inf>NA/CC) into NiCo<inf>2</inf>S<inf>4</inf>NA/CC, which is used as an efficient bifunctional electrocatalyst for water splitting with good durability and superior activity in 1.0 M KOH. This NiCo<inf>2</inf>S<inf>4</inf>NA/CC electrode produces 100 mA cm<sup>-2</sup>at an overpotential of 305 mV for hydrogen evolution and 100 mA cm<sup>-2</sup>at an overpotential of 340 mV for oxygen evolution. To afford a 10 mA cm<sup>-2</sup>water-splitting current, the alkaline water electrolyzer made from NiCo<inf>2</inf>S<inf>4</inf>NA/CC needs a cell voltage of 1.68 V, which is 300 mV less than that for NiCo<inf>2</inf>O<inf>4</inf>NA/CC, and has good stability. ©2015 The Royal Society of Chemistry.
