摘要：

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.
