摘要

本研究以硼氢化钠为还原剂,琥珀酸钠为保护剂,采用化学还原法制备了Sn/Ag纳米颗粒复合材料。XRD、EDX和TEM分析表明,制备的Sn/Ag复合纳米颗粒平均粒径为4.37 + 0.44 nm。在应用中,对Sn纳米颗粒和Sn/Ag纳米颗粒复合材料样品进行了LSV分析,结果表明,在-0.83V电位下,Sn/Ag纳米颗粒复合材料产生的电流(4.10 × 10-6 A)高于Sn纳米颗粒(3.47 × 10-6 A)。

Synthesis and Characterization of Sn/Ag Nanoparticle Composite as Electro-Catalyst for Fuel Cell
In this research, Sn/Ag nanoparticle composite was produced by using chemical reduction method with the aids of sodium borohydride as reducing agent and sodium succinate as protective agent. The XRD, EDX, and TEM analyses showed that the Sn/Ag nanoparticle composite was formed with an average particle size of 4.37 + 0.44 nm. For the application, LSV analysis was done on Sn nanoparticle and Sn/Ag nanoparticle composite samples, and the analysis showed current produced from Sn/Ag nanoparticle composite (4.10 × 10-6 A) is higher than Sn nanoparticle (3.47 × 10-6 A) at the potential of -0.83V.
