摘要
Oxygen evolution reaction （OER） electrolysis, as an important reaction involved in water splitting and rechargeable metal-air batteries, has attracted increasing attention for clean energy generation and efficient energy storage. Nickel/iron （NiFe）-based compounds have been known as active OER catalysts since the last century, and renewed interest has been witnessed in recent years on developing advanced NiFe-based materials for better activity and stability. In this review, we present the early discovery and recent progress on NiFe-based OER electrocatalysts in terms of chemical properties, synthetic methodologies and catalytic performances. The advantages and disadvantages of each class of NiFe-based compounds are summarized, including NiFe alloys, electrodeposited films and layered double hydroxide nanoplates. Some mechanistic studies of the active phase of NiFe-based compounds are introduced and discussed to give insight into the nature of active catalytic sites, which could facilitate further improving NiFe based OER electrocatalysts. Finally, some applications of NiFe- based compounds for OER are described, including the development of an electrolyzer operating with a single AAA battery with voltage below 1.5 V and high performance rechargeable Zn-air batteries.
当重要反应在水切开和可充电的金属空气电池包含了，氧进化反应(OER ) 电解为干净精力产生和有效精力存储吸引了增加的注意。镍 / 铁(NiFe ) 基于混合物自从最后世纪，和更新的兴趣在为更好的活动和稳定性开发先进基于 NiFe 的材料上在最近的年里被见证，作为活跃 OER 催化剂被知道了。在这评论，我们在场基于 NiFe 的 OER electrocatalysts 上的早发现和最近的进步以化学性质，合成方法论和催化表演。基于 NiFe 的混合物的每个班的优点和劣势被总结，包括 NiFe 合金， electrodeposited 电影和分层的双氢氧化物 nanoplates。基于 NiFe 的混合物的活跃阶段的一些机械学的研究被介绍并且讨论了给卓见进活跃催化地点的性质，它能便于进一步改善的 NiFe 基于的 OER electrocatalysts。最后，为 OER 的基于 NiFe 的混合物的一些应用程序被描述，包括与有在 1.5 V 和高效下面的电压的一节单个 AAA 电池操作可充电的 Zn 空气电池的 electrolyzer 的开发。
