Nickel–iron and cobalt–iron (oxy)hydroxides are state-of-the-art electrocatalysts for oxygen production in alkaline conditions. Now, the addition of high-valent dopants has been demonstrated to further propel the catalytic rate in these materials by an order of magnitude.

在碱性介质中更快地制氢

镍铁和钴铁（氧）氢氧化物是在碱性条件下产生氧气的最先进的电催化剂。现在，已证明添加高价掺杂剂可进一步将这些材料中的催化速率提高一个数量级。
