Click-Functionalized Ru(II) Complexes for Dye-Sensitized Solar Cells

Michael Graetzel, Paul Joseph Dyson, Shaik Mohammed Zakeeruddin, Nuttapol Pootrakulchote, Ryan Dykeman, Amaresh Mishra

Three heteroleptic ruthenium complexes incorporating new ancillary ligands synthesized by sequential connection of different alkyl functionalities with triazole as a linker are prepared using click chemistry. These sensitizers exhibit low-energy metal-to-l ...

Supported nitrogen-modified Pd nanoparticles for the selective hydrogenation of 1-hexyne

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Rocio Micaela Crespo Quesada, Ryan Dykeman

2,2′-Bipyridine (bipy) and an imidazolium-functionalized bipy ligand were used in the synthesis of palladium nanoparticles in water and in ionic liquid. The function of such ligands was twofold: first, as stabilizing agents to prevent the agglomeration of ...

4,4' Functionalized 2,2'-Bipyridines : Synthesis and Applications as Catalytically Active Nanoparticle Stabilizers and Ligands for Ruthenium Dye Molecules

Ryan Dykeman

This thesis presents two applications of 2,2'-bipyridine (bipy) derivatives, the first involves their use as stabilizers for nanoparticle (NP) catalysts and the second is concerned with the use of bipy ligands for ruthenium dye molecules applied in dye sen ...

Hydrodeoxygenation of lignin-derived phenols into alkanes by using nanoparticle catalysts combined with Bronsted acidic ionic liquids

Paul Joseph Dyson, Ning Yan, Yuan Yuan, Ryan Dykeman

The transformation of lignin-derived phenolic compds. to alkanes was achieved using catalysts based on Bronsted acidic ionic liqs. (ILs). The catalytic system is composed of metal nanoparticles (NPs) and a functionalized Bronsted acidic IL immobilized in a ...
