Oxygen transport membranes (OTM) are a promising technology that improves current oxygen separation methods by lowering costs and increasing efficiency. OTMs are composed of metal oxides which transport both oxygen ions and electrons across a membrane. Perovskite materials have been proposed as OTMs. This project focuses on synthesizing three perovskites with varying composition using three different synthesis techniques. The compounds were synthesized using a solid-state ceramic method and two different sol-gel methods that involve the use of citrate/EDTA and citrate/ethylene glycol to understand the effect of synthesis technique on the underlying structure. The structure of all compounds was investigated using powder X- ray diffractometry. It has been shown that all three compounds can be successfully synthesized via all three synthesis routes and the details of the crystal structure analysis is ongoing.

Role: I was involved in synthesizing all three compounds using all three techniques listed in the abstract. I also analyzed these compounds using X-ray diffraction and compared the data using the Inorganic Crystal Structure Database (ICSD).
