The oxygen evolution reaction (OER) is a well-recognized bottleneck reaction in overall water splitting because of its multi-electron transfer steps and sluggish reaction kinetics, which creates significant difficulties in delivering appreciable current. Both active and robust OER catalysts are highly desired to boost overall water splitting. Recently, two-dimensional and self-supported transition metal oxides and (oxy)hydroxides (2D-SS-TMOs) have received particular attention due to their high intrinsic activity, large electrolyte accessible surface area, decent electrical conductivity, and great structural stability. In this review, the recent developments of 2D-SS-TMO OER catalysts are summarized. Both fabrication methods and the strategies for activity enhancement of 2D-SS-TMOs are also reviewed. In view of their great OER performances, 2D-SS-TMOs demonstrated in photoelectrochemical water splitting and lithium air batteries are also discussed.

自支撑二维过渡金属氧化物和（氧）氢氧化物作为氧释放反应催化剂的最新进展

氧气析出反应（OER）由于其多电子转移步骤和缓慢的反应动力学，在整个水分解中是公认的瓶颈反应，这在输送可观电流方面造成了很大困难。强烈需要活性和坚固的OER催化剂来促进总水分解。最近，由于二维和自支撑的过渡金属氧化物和（羟基）氢氧化物（2D-SS-TMO）具有很高的固有活性，较大的电解质可及表面积，良好的导电性和良好的结构稳定性，因此受到了特别的关注。在这篇综述中，总结了2D-SS-TMO OER催化剂的最新发展。还审查了2D-SS-TMO的制造方法和增强活性的策略。鉴于他们出色的OER表现，
