摘　　要：目的通过优化合成条件,合成高结晶度的管状金属银。方法以乙二醇为溶剂和还原剂,通过考察反应时间、反应温度以及表面活性剂对产物形貌的影响,确定合成管状金属银的最优化条件。并利用XRD、SEM等技术对所得产物进行表征。结果合成了高结晶度、形貌完美的管状金属银。结论在醇热反应体系中,当反应温度高于90℃时,可以获得到纯态的金属银;通过向反应体系中加入一定量的表面活性剂,可以有效改善产物形貌,合成管状金属银。Objective--Tubal silver materials with high crystalhmty were syntlaeslzea oy opnmtzmg synthesis conditions. Methods--Glycol was used as solvent and reducing agent. Effects of reaction time, reaction temperature and surfactants on the morphology of products were investigated to determine optimized synthesis conditions, and the products were characterized by such technologies as XRD and SEM. Results--The tubal silver with high crystallinity and perfect morphology has been success- fully synthesized. Conclusion---In alcohol-thermal system, the pure silver materials can be synthesized when the reaction temperature is beyond 90 ℃. By means of adding some surfactants into the reaction system, the morphology of tubal silver can be improved.
