Potential use of platinum doped ceria (Ce 0.95 Pt 0.05 O2) through low temperature solution combustion method

The significant aim of the research work was mainly focused on the effective development and catalytic applications of platinum doped ceria (Ce0.95Pt0.05O2) through a low temperature solution combustion method using glycine as fuel. The synthesized Pt doped CeO2 (Ce0.95Pt0.05O2) was prepared by taking stoichiometric amounts of ceric ammonium nitrate, platinum chloride and glycine by solution combustion method. The comprehensive characterization of the mixed metal oxide was achieved through various analytical techniques. The accurate size and morphology of the platinum doped metal oxide was studied by scanning electron microscope (SEM) and energy dispersive X-ray analysis (EDX). The phase composition of the platinum substituted ceria (Ce0.95Pt0.05O2) was confirmed from powder X-ray Diffractometer (PXRD). The functional groups are analyzed by Fourier transfer infrared spectroscopy (FT-IR), UV-Visible spectroscopy and TEM analysis. The precursor of platinum used in the catalyst synthesis, as well as the properties of the CeO2 support, was both found to significantly influence catalytic performance. The metal oxide doped with Pt exhibits superior catalytic properties along with its various applications.
