Abstract: Metallic 1T phase molybdenum disulfide(1T MoS2) is an excellent catalyst due to the abundant active sites and good conductivity. However, complex synthesis and unstable nature of 1T MoS2 still limit its practical application. Herein, we propose a simple method to trigger the phase transition of MoS2. This phase transition is first predicted by density functional theory(DFT) calculations and then confirmed by Raman spectroscopy and high-resolution transmission electron microscopy(HRTEM). 1T MoS2/Cu2O heterostructure catalyst is then developed, showing enhanced photocatalytic hydrogen evolution.
