Abstract

Focusing on the global energy crisis and facing major national needs, scientists explore the field of hydrogen production materials by electrolysis of water. As a new catalyst material, MoS₂ shows high catalytic efficiency in the electrolysis of water for hydrogen production. It, therefore, has the potential to replace Pt precious metals as a catalytic material in hydrogen precipitation reactions[1]. MoS₂ is based on nanomaterials and its catalytic activity and intrinsic properties can be improved by modulation of the morphological structure. The process of preparing MoS₂ in nanospheres, amorphous, bread-shaped and flower-shaped MoS₂ is discussed in this study. The effect of adding surfactants or other solvents to the synthesis on the morphological structure is investigated in comparison with the efficiency of hydrogen precipitation. Finally, ideas for improving the catalytic efficiency are presented and future developments of MoS₂ materials are foreseen. Studies have found that the morphology and structure of MoS₂ can be changed by solvents and surfactants. The catalytic activity of nano-microsphere and flower-like is higher than that of bread-like MoS₂.
