Polyol-Mediated Synthesis of MoS2 Nanosheets Using Sulfur Powder as the Sulfur Source
摘要
Abstract
MoS2 nanosheets are prepared with sulfur powder and Na2MoO4 by a one-pot two-phase method at 170-200 C for 8 h.In addition,a three-step growth mechanism based on the aggregation and coalescence model is proposed.The reassembly of sulfur powder ensures the transformation from sulfur powder to H2S to reduce Na2MoO4 and plays a key role in the successful preparation of MoS2 nanosheets.The as-prepared MoS2 nanosheets are rich in unsaturated sulfur atoms,probably resulting from the dislocation cores of the MoS2 nanosheets,which have been found to be beneficial for hydrogen evolution reaction catalysis.The method and growth mechanism adopted in this study may be applied to other transition metal dichalogenides for similar structures.The facile and green method provides an alternative for the preparation of MoS2 nanosheets.关键词
