Type: dissertation
Abstract: Sustainable hydrogen production photoelectrochemically or photocatalytically is a desirable process that has the potential to allow hydrogen to be utilized as a carbon free fuel.In order for this method to become commercially viable, scientific advances must be made on current technologies.Sustainable hydrogen production photocatalytically is projected to be more cost effective than hydrogen production photoelectrochemically, however significant scientific studies need to made and its future is uncertain.We envision a system of molecular electrocatalysts and colloidal photosensitizers for hydrogen production via photocatalysis.In Chapter 2, a library of molecular electrocatalysts are synthesized and their ability to perform hydrogen evolution electrocatalytically is explored.These molecules are found to be competent hydrogen evolution catalysts in nonaqueous solvents, albeit with high overpotentials.The parent metalloligand's ability to be a nucleophile toward a variety of cations lead us to study its interactions with CdSe in Chapter 3. In this Chapter, an electrochemical method for analyzing the equilibrium interactions between CdSe nanocrystals and small molecules is investigated.This technique
