چکیده انگلیسی
Addressed herein, a highly effective and monodisperse Pt/L@rGO nanocatalysts were successfully synthesized by using different types of ligands (pentylamine, Pt/PA@rGO and tripentylamine, Pt/TPA@rGO) and the impact of ligand on catalytic activity of the prepared nanomaterials have been examined for methanol oxidation. An easy and facile ultrasonication method was applied to produce highly efficient, monodispersed and durable (Pt) NPs dispersed on reduced graphene oxides (rGO). The structure morphology, composition and properties of Pt/L@rGO NPs were characterized by using different techniques such as ICP-OES, XPS, TEM, HRTEM, and XRD methods. A different ligand based monodisperse Pt (0) nanocatalysts have been compared with each other and commercial catalysts in terms of catalytic performance, life-time and reusability of catalyst for methanol oxidation reaction in THF at room temperature. All experimental results demonstrate the highly stable and reusable rGO furnished Pt (0) nanomaterials and their excellent catalytic performance in the methanol oxidation reactions at room temperature.
