采用一步溶剂热分解法制备了Bi2S3纳米线，考察了溶剂、反应温度和反应时间对Bi2S3纳米线形成的影响。产率高达98%。Bi2S3纳米线的颗粒尺寸受溶剂的选择控制。提出了SDP法制备Bi2S3纳米线的可能机制。本技术有望在温和的条件下合成其他纳米结构的金属硫化物。
A novel one-step solvothermal decomposition process (SDP) was successfully developed for fabrication of Bi2S3 nanowires via a reaction between BiCl3 and thiourea in polar solvents at 140 degrees C for 6-12 h. The influence of solvents, reaction temperature, and reaction time on the formation of Bi2S3 nanowires was investigated. The yield was as high as 98%. The particle sizes of Bi2S3 nanowires are controlled by the choice of solvents. The possible formation mechanism of Bi2S3 nanowires via the so-called SDP method is proposed. The present technique is expected to synthesize other nanostructural metal chalcogenides under mild conditions.
