基于β-环糊精单分散银纳米粒子的绿色合成

摘要

Silver nanoparticles with diameter between 10～30 nm were synthesized by one-pot method using silver nitrate as raw material, β-cyclodextrin as reducing agent and protective agent.The structures were characterized by UV-Vis, FT-IR, XRD and TEM.The effects of pH, reaction temperature and γ[n(1)∶n(AgNO3)] on the reaction were investigated and the mechanism was further discussed.%以硝酸银为原料,β-环糊精为还原剂和保护剂,一步法合成了粒径为10～30 nm的单分散银纳米粒子,其结构经UV-Vis, FT-IR, XRD和TEM表征.研究了pH、反应温度和γ[n(1)∶n(AgNO3)]对反应的影响,并提出了银纳米粒子的形成机制.
