中文摘要: 以钼酸钠为钼源，硫脲为硫源，分别加入两种不同的还原剂（盐酸羟胺、草酸），采用水热法制备了形貌规整的二硫化钼微球花。结果表明：当体系中初始钼硫比小于或等于1∶5时，产物为纯净的二硫化钼；随着钼硫比的减小，所得产品粒径也逐步增大。两种不同还原剂作用下，均可制备得到布满褶皱状薄片的二硫化钼球花。盐酸羟胺还原剂作用下所得产物比草酸还原剂作用下所得产物的粒径要稍大，但花瓣状更清晰，褶皱程度更高，团聚程度也较轻。并对其原因做了阐述。
Abstract:The molybdenum disulfide flower-sphere were hydrothermally synthesized by reaction of Na2MoO4, CS(NH2)2, and different reductants (NH2OH·HCl, H2C2O4). The results showed that the product was nearly pure MoS2 when mole ratio of Mo to S was less than or equal to 1∶5. The particle size increased as the mole ratio of Mo to S reduced. The MoS2 microspheres had rough surfaces and were of sheetlike structures in the two different systems. The product in the system with NH2OH·HCl as the reductant had bigger particle size, clearer petal-sheets, coarser surface, and slighter agglomeration than that in the system with H2C2O4 as reductant. The related reason was explained.
