Herein, we have reported an easily synthesized CoS2/Ni3S2/CoNiOx water oxidation catalyst with excellent catalytic activity and superior durability. The as-prepared catalyst required overpotential (η) as low as 256 mV to exhibit a current density of 10 mA cm-2 in 1.0 M KOH. Remarkably, it sustained a current density of 1 A cm-2 for one week in 30% KOH solution with only 25 mV increment of η. Thus, it is a hopeful candidate as a highly-effective water oxidation electrode in practical applications.
在此，我们报道了一种易于合成的 CoS2/Ni3S2/CoNiOx 水氧化催化剂，该催化剂具有优异的催化活性和卓越的耐久性。所制备的催化剂仅需 256 mV 的过电势 (η) 即可在 1.0 M KOH 中表现出 10 mA cm-2 的电流密度。值得注意的是，它在 30% KOH 溶液中能够持续稳定地产生 1 A cm-2 的电流密度，且 η 仅增加了 25 mV。因此，它是一种很有前途的高效水氧化电极候选材料，有望在实际应用中得到应用。
