碳化硅纳米材料的溶剂热合成

本文综述了溶剂热法制备一系列碳化硅纳米材料的研究,包括一维纳米线、纳米带、纳米棒、二维纳米片及空心球等;同时,碳源过量时可形成碳包覆碳化硅的复合材料。使用废塑料作为碳源合成了碳化硅纳米材料,为废塑料的回收再利用提供了新途径。通过使用碘、硫等添加剂,有效降低了合成温度,显示出溶剂热技术在制备碳化硅方面的独特优势。

Solvothermal Synthesis of Silicon Carbide Nanomaterials

The study on the preparation of a series of silicon carbide nanomaterials, including 1D nanowires, nanobelts, nanorods, 2D nanosheets, hollow spheres, and so on, via solvothermal technique is summarized in this article. Meanwhile, SiC@C composite materials can be produced in the case of excess carbon sources. Silicon carbide nanomaterials can also be prepared by using waste plastics as carbon source, which provides a new route to the recycling and reutilization of waste plastics. Moreover, the synthesis temperature can be effectively decreased by using iodine and sulfur as additives, indicating the unique advantage of solvothermal technique in the preparation of silicon carbide nanomaterials.
