Flame Synthesis of Nanoscale Cu/CeO2 for Fuel Cell Applications Hillary Sadoff In collaboration with Osifo Ahuemonkhan, Dmitri Iarikov, Sicong Hou, Dr. Ranjan Pati and Professor Sheryl Ehrman.

Overview of Results

• High surface area particles are prepared in flame spray pyrolysis method.
• Particles prepared are in the nanoscale range (from TEM & BET).
• Ceria surface is enriched with Cu²⁺ ion (from XPS)
• Etching results show that the Cu²⁺ may be present in the CeO₂ lattice.
• Small amount of carbon present in the materials (TGA & FTIR).
