Using phosphine-based organic ligands, it is possible to design materials with pore dimensions and topologies that impart such properties. More specifically, the chemistry of the phosphine-based systems offers additional possibilities that have not yet been explored in metal-organic framework synthesis. These include the incorporation of polar (R3P=X) or ionic (R3P+R') organic species into the PCMs, which may enhance their solid-state properties.
Polymer-capped metal nanoparticles are examples of model catalysts, which have favorable surface-area:volume ratios and defined surface structure. In collaboration with groups in the UK and the USA, the Humphrey Research Group is interested in finding improved routes toward the solution-phase synthesis of near-monodisperse noble metal nanoparticles. The nanoparticle catalysts may then be used directly or when anchored on support media (e.g. silica), to study important small organic molecule transformations in the solution- or vapor-phase.

Now that you've used EUREKA to identify a faculty member whose research interests match your own, read about getting involved in research at The University of Texas at Austin.
The Office of Undergraduate Research recommends that you attend an info session before contacting faculty members about research opportunities. We'll cover the steps to getting involved, tips for contacting faculty, funding possibilities, and options for course credit.
If you aren't able to attend an info session, contact the Office of Undergraduate Research to schedule an appointment with an advisor.
