Water oxidation has become very popular due to its prime role in water splitting and metal-air batteries. Thus, the development of efficient, abundant, and economical catalysts, as well as electrode design, is very demanding today. In this review, we have discussed the principles of electrocatalytic water oxidation reaction (WOR), the electrocatalyst and electrode design strategies for the most efficient results, and recent advancement in the oxygen evolution reaction (OER) catalyst design. Finally, we have discussed the use of OER in the Oxygen Maker (OM) design with the example of OM REDOX by Solaire Initiative Private Ltd. The review clearly summarizes the future directions and applications for sustainable energy utilization with the help of water splitting and the way forward to develop better cell designs with electrodes and catalysts for practical applications. We hope this review will offer a basic understanding of the OER process and WOR in general along with the standard parameters to evaluate the performance and encourage more WOR-based profound innovations to make their way from the lab to the market following the example of OM REDOX.
由于水氧化在水分解和金属空气电池中起着重要作用，它已变得非常热门。因此，如今开发高效、丰富且经济的催化剂以及电极设计极具挑战性。在本综述中，我们讨论了电催化水氧化反应（WOR）的原理、实现最有效结果的电催化剂和电极设计策略，以及析氧反应（OER）催化剂设计的最新进展。最后，我们以Solaire Initiative Private Ltd的OM REDOX为例，讨论了OER在制氧机（OM）设计中的应用。该综述清晰地总结了借助水分解实现可持续能源利用的未来方向和应用，以及开发用于实际应用的带有电极和催化剂的更好电池设计的前进方向。我们希望本综述能提供对OER过程和WOR总体的基本理解，以及评估性能的标准参数，并鼓励更多基于WOR的深刻创新，以OM REDOX为例，使其从实验室走向市场。
