Silver nanoparticles (Ag NPs) embedded in poly(perfluorosulfonic) acid cation-exchange membrane (Nafion-211) were synthesized by in situ reductions of Ag⁺ ions by sodium borohydride at room temperature and formamide at 65 °C. The formamide-reduction formed Ag NPs uniformly distributed in the membrane matrix. Therefore, the formamide-reduced Ag NPs embedded membranes were used for the sorption-preconcentration of Mercury (Hg)²⁺ ions by the galvanic reaction with Ag NPs in the membrane matrix. The replacement of Ag⁰ in NPs with Hg²⁺ ions resulted in the formation of Hg⁰ accumulated as nanodroplets in the membrane matrix as indicated by the field emission scanning electron microscopy studies. The sorption of Hg²⁺ ions via galvanic reaction in the Nafion membrane was found to be maximum (>93%) from pH = 2.5 to pH = 6.5. The Ag NPs embedded membrane was studied for Hg²⁺ ions sorption from the aqueous samples by radiotracer (²⁰³Hg), spectrophotometry, energy dispersive X-ray fluorescence and cold vapor atomic absorption spectrophotometry. This membrane was successfully applied for the determination and quantification of Hg²⁺ ions in the real water samples and safe storage of Hg for the remediation objective. The Hg⁰ embedded membrane was also found to be promising as the dip catalyst in the representative organic transformation of phenylacetylene to acetophenone. The Hg⁰ embedded membrane dip catalyst was reused in four consecutive cycles under similar conditions and found to be successful by giving an almost similar yield (%) of the product. This demonstrated a possibility of safe application of Hg⁰ stored in the matrix of poly(perfluorosulfonate) membrane for catalysis.

嵌入聚（全氟磺酸）酸阳离子交换膜（Nafion-211）中的银纳米粒子（Ag NPs）是通过在室温下用硼氢化钠和甲酰胺在 65°C 下原位还原 Ag ⁺离子来合成的。甲酰胺还原形成的 Ag NPs 均匀分布在膜基质中。因此，甲酰胺还原的 Ag NPs 嵌入膜用于通过与膜基质中的 Ag NPs 的电流反应对汞 (Hg) ²⁺离子进行吸附预浓缩。用Hg ²⁺离子替换NPs 中的Ag ⁰导致形成Hg ⁰作为膜基质中的纳米液滴积累，如场发射扫描电子显微镜研究所示。汞的吸附发现通过 Nafion 膜中的电流反应产生的²⁺离子从 pH = 2.5 到 pH = 6.5 达到最大值 (>93%)。通过放射性示踪剂 ( ²⁰³ Hg)、分光光度法、能量色散 X 射线荧光和冷蒸气原子吸收分光光度法研究了 Ag NPs 嵌入膜从水样中吸附Hg ²⁺离子。该膜已成功应用于实际水样中 Hg ²⁺离子的测定和定量，以及用于修复目标的汞的安全储存。还发现嵌入Hg ^{0 的}膜有望用作苯乙炔向苯乙酮的代表性有机转化过程中的浸渍催化剂。汞⁰嵌入的膜浸渍催化剂在类似条件下连续四个循环重复使用，并发现通过提供几乎相似的产物产率 (%) 是成功的。这证明了安全应用储存在聚（全氟磺酸盐）膜基质中的 Hg ⁰进行催化的可能性。
