Project Description and Objectives
The hydrogen evolution reaction (HER) of proton exchange membrane water electrolysis often uses Pt precious metal catalysts, and the high cost to some extent limits its commercial development. MoS2 is widely used in the field of electrocatalysis due to its unique layered structure, especially as a HER catalyst for water electrolysis. The HER performance of MoS2 depends on its different phase compositions and microstructure. Previous studies have shown that 1T metal phase molybdenum disulfide rich in high conductivity has high HER performance, and the ultra-thin nano-layered MoS2 structure rich in high active edges also exhibits good HER activity. However, obtaining highly stable 1T metal phase molybdenum disulfide is currently a challenge, and the intrinsic structure-activity relationship between the phase composition and microstructure of molybdenum disulfide and its hydrogen evolution activity is not yet clear. This study will focus on the different microstructures and phase transitions of 1T and 2H molybdenum disulfide, exploring the HER performance of molybdenum disulfide with different phase compositions and microstructures, and revealing its structure-activity relationship at the molecular and atomic scales. This project is of great significance for the development of non-precious metal catalysts in the field of electrolytic water hydrogen production.
