The complicated synthesis procedure and the unstable nature of 1T MoS2 vastly impede its practical application although it has shown a high performance for many different applications. Herein, we have synthesized ultrastable 1T phase MoS2 embedded in CoOOH by a facile one-pot strategy and achieved a high overall water splitting activity. The amorphous CoOOH in this heterostructure not only exhibits high oxygen evolution reaction activity, but also anchors and stabilizes the 1T MoS2 as vertically aligned single layers. This novel method gives new insight into developing stable and active atomically thin transition metal dichalcogenide heterostructures.
尽管 1T MoS2 具有多种不同应用的优异性能，但复杂的合成工艺和不稳定的性质极大地阻碍了其实际应用。在此，我们通过简便的一锅法合成了嵌入在 CoOOH 中的超稳定 1T 相 MoS2，并实现了高整体水分解活性。该异质结构中的非晶态 CoOOH 不仅表现出高的析氧反应活性，而且还固定和稳定了垂直排列的单层 1T MoS2。这种新方法为开发稳定且活性的原子层状过渡金属二卤化物异质结构提供了新的思路。
