Preparation and Characterization of Chloride-Free Alumina-Supported Platinum Catalysts

摘要

Supported precious metal catalysts are extensively used as efficient catalysts. This kind of catalysts, particularly chloride-free catalysts, synthesized using organoplatinum compounds as precursors has attracted immense research interest compared to their parent metals due to their unique physico-chemical properties.The main objective of this research is to prepare and characterize the chloride-free alumina-supported platinum catalysts. An organometallic compound of ammonium bisoxalatoplatinate(II) hydrate was used to prepare unsupported and alumina supported platinum catalysts. A series method including IR, XRD, SEM, TEM, EDA, and XPS was used to characterize samples. The research shows that ammonium bisoxalatoplatinate(II) hydrate could be synthesized and used to prepare unsupported and alumina supported platinum free of chloride impurities.
