Electronic Thesis and Dissertation Repository
This thesis investigates the electronic structure of Pt for catalysis applications. The importance of the Pt 5d band is discussed in terms of the bonding capability of Pt. The oxygen reduction reaction in proton exchange membrane fuel cells is chosen as the catalytic reaction model to illustrate the effect of Pt 5d states on Pt-O interaction. Pt-based bimetallic systems are introduced as a solution for the high price and limited resources of Pt. Despite lower usage of Pt, the tuning capability to optimize the Pt 5d band in bimetallic catalysts is supposed to provide superior catalytic activity. Advanced synchrotron X-ray …

Scripps Senior Theses
Alkanes are some of the most abundant organic molecules, yet currently there are no efficient ways of directly converting them to more functional molecules. One viable method of direct functionalization is C–H bond activation by transition metal catalysts. The focus of this research has been the synthesis of a new Pt(II) pincer complex to be used in mechanistic investigations of C–H activation, as well as the beginnings of those investigations. The complex [NNON]PtMe was successfully synthesized. Reactions with various acids indicated that [NNON]PtMe is capable of reductively eliminating methane after addition of two equivalents of acid. …
