Research The Holland group studies compounds containing inexpensive metals like iron and cobalt, with the goal of understanding their reactions in detail and increasing their potential for use in catalysis. We do this by preparing new molecules that are highly reactive. In some cases, the compounds have weak metal-ligand multiple bonds, and in others there are open sites for reactions on the metal. We specialize in compounds where the metal has very few bonds, and have done many detailed studies on this rare and exciting type of compound.
A major part of our research program has focused on iron complexes for nitrogen fixation. This is relevant to the industrial Haber-Bosch process for fertilizer production, and to nitrogenase, the natural enzyme that converts atmospheric nitrogen into ammonia. Other research in our laboratory has addressed solar production of hydrogen, catalytic alkene and fluorocarbon reduction, redox-active ligands, engineered metalloproteins, and fundamental organometallic mechanisms. More detail on our research is available at the Holland Group Web site.
Our research provides an interdisciplinary training environment that develops students’ skills in synthesis, biological inorganic chemistry, organometallic chemistry, mechanistic techniques, and spectroscopy.
