以液相合成法为基础,选用Mn(CH3COO)2.4H2O和硫粉为原料,首次通过多次注入前驱体的方法,成功制备得到了硫化锰纳米棒,研究了不同的制备条件如注入前驱体的量及时间对MnS纳米棒形状及分布的影响。根据实验结果,对其生长机理进行了初步的探讨。作者通过对纳米材料的形貌控制合成研究,探索可控合成晶粒尺寸均匀、分散良好的纳米材料的方法,探讨不同纳米材料的晶粒生长行为,进而揭示其形成机理,并研究其微结构与性能之间的关系,其结论将对类似纳米材料的制备提供实验依据和理论支持。
Based on the liquid-phase synthesis method, Mn (CH3COO) 2.4H2O and sulfur powder were selected as the raw materials. Manganese sulfide nanorods were successfully prepared by multiple injections of precursors for the first time. Different preparation conditions such as precursor The amount and time of MnS nanorods shape and distribution. According to the experimental results, the growth mechanism was preliminarily discussed. Based on the study of morphology and control synthesis of nanomaterials, the authors explored a method for controlled synthesis of nanosized materials with uniform size and good dispersion, and discussed the grain growth behavior of different nanomaterials, then revealed their formation mechanism and studied their microstructure And the relationship between performance, the conclusion will provide experimental evidence and theoretical support for the preparation of similar nanomaterials.
