Synthesis of Pt-3d transition metal bimetallic intermetallics using a block copolymer
Research Mentor(s)
Rider, David A. (Materials scientist)
Description
The use of Pt-3d transition metal bimetallic intermetallic nanoparticles as a CO oxidizing agent in fuel cells shows much promise as a less expensive and more efficient material than pure Pt. In this project, polymer micelles were used to protect and structurally organize Pt3Ti nanoparticles, which were then deposited as a thin film onto substrates and annealed. The samples were analyzed using DLS, AFM, XPS, and XRD to determine the interaction between the metals and the polymer, as well as to confirm the synthesis of the bimetallic intermetallic. Confirmation for the polymer absorbing the metal compounds was confirmed using DLS, and verification for the formation of Pt3Ti was obtained using XRD. Structural organization of the bimetallic intermetallic due to the use of polymer has not yet been confirmed.
