Development of efficient and renewable electrocatalytic systems is foundational to creation of effective means to produce solar fuels. Many redox enzymes are functional electrocatalysts when immobilized on an electrode, but long-term stability of isolated proteins limits use in applications. Thus there is interest in developing bio-inspired functional catalysts or electrocatalytic systems based on living organisms. This dissertation describes efforts to create both synthetic and biological electrochemical systems for electrocatalytic hydrogen production. The first part of this dissertation describes the preparation of three different types of proton reduction catalysts. First, four bioinspired diiron complexes of the form (μ-SRS)Fe(CO)3[Fe(CO)(N-N)] for SRS = …

Redox enzymes represent a big group of proteins and they serve as catalysts for biological processes that involve electron transfer. These proteins contain a redox center that determines their functional properties, and hence, altering this center or incorporating non-biological redox cofactor to proteins has been used as a means to generate redox proteins with desirable activities for biological and chemical applications. Porphyrins and Fe-S clusters are among the most common cofactors that biology employs for electron transfer processes and there have been many studies on potential activities that they offer in redox reactions. In this dissertation, redox activity of Fe-S …
