介绍利用气相诱导前驱体共还原方法制备了Sb2Se3一维纳米结构。利用XRD、EDS、FESEM和TEM等手段,研究了联氨、乙二胺、氨水等不同种类还原剂对Sb2Se3纳米棒生长过程的影响。研究表明,在气相还原剂诱导前驱体溶液共还原的过程中,联氨是一种较好的还原剂,其作为亲核试剂可有效的控制化学反应和形核速率,诱导前驱体中的Se4+和SbIII被还原形核并自组装形成一维纳米产物。同时,乙二醇溶剂起到了结构稳定剂的作用,随着反应体系的冷却,溶剂的挥发释放过程对纳米产物的形成有重要影响。
This paper describes the synthesis of Sb2Se3 one-dimensional nanostructures by gas-induced precursor co-reduction method. The effects of different reducing agents such as hydrazine, ethylenediamine and ammonia on the growth of Sb2Se3 nanorods were studied by means of XRD, EDS, FESEM and TEM. The results show that hydrazine is a good reductant during the process of reductive agent-induced precursor solution co-reduction. As a nucleophile, hydrazine can effectively control the chemical reaction and nucleation rate, and induce the formation of Se4 + And SbIII are reduced to nucleate and self-assemble to form one-dimensional nano-products. At the same time, ethylene glycol has played a role as a structural stabilizer. With the cooling of the reaction system, the volatilization and release of the solvent have an important influence on the formation of nano-products.
