In this report, silver nanoparticles (Ag NPs) anchored reduced graphene oxide (rGO) sheets (rGO/Ag) nanohybrid has been explored as anode material in direct methanol fuel cells (DMFCs). The synthesized rGO/Ag nanohybrid is characterized by XRD, XPS, FTIR spectroscopy and HRTEM techniques. Cyclic voltammograms demonstrate that the rGO/Ag nanohybrid exhibits higher electrocatalytic activity in comparison to rGO sheets for methanol oxidation reaction (MOR). This enhancement is attributed to the synergetic effect produced by the presence of more active sites provided by Ag NPs anchored on a conducting network of large surface area rGO sheets.

在本报告中，已研究了锚固纳米氧化还原银（rGO）片（rGO / Ag）纳米杂化银纳米颗粒作为直接甲醇燃料电池（DMFC）中的阳极材料。通过XRD，XPS，FTIR光谱和HRTEM技术对合成的rGO / Ag纳米杂化物进行表征。循环伏安图表明，与用于甲醇氧化反应（MOR）的rGO薄片相比，rGO / Ag纳米杂化物表现出更高的电催化活性。这种增强归因于由锚定在大表面积rGO片的导电网络上的Ag NPs提供的更多活性位点所产生的协同效应。
