摘要

用x射线照射含有AuIII离子的聚（1-乙烯基咪唑）乙醇水溶液可生成金纳米颗粒（AuNPs），其平均大小由介质的pH值决定。得到的结果证明了在中性pH下形成稳定的超小AuNPs （<2 nm）的一个突出例子。

Effect of pH on radiation-induced synthesis of gold nanoparticles in solutions of poly(1-vinylimidazole)–AuIII complexes

Irradiation of an aqueous ethanol solution of poly(1-vinylimidazole) containing Au^III ions with X-rays leads to the generation of gold nanoparticles (AuNPs) with an average size determined by the pH value of the medium. The results obtained demonstrate a prominent example of the formation of stable ultrasmall AuNPs (<2 nm) at neutral pH.

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
