There is currently a global energy crisis, which is in desperate need of solutions. New energy sources are required that will not pollute as much as our longstanding reliance on nonrenewable fossil fuels as an energy source. This pollution involves large amounts of greenhouse gas emissions, predominantly carbon dioxide (CO2), that contribute to environmental problems such as climate change. In this context, a fairly recent research direction to address this problem is the development of transition metal catalysts that can convert CO2 into reduced carbon products that can serve as chemical fuels. This work focuses on the …

Alternative energy is more imperative than ever as we continue to exhaust nonrenewable resources. There is promise in artificial hydrogenases that produce hydrogen gas which can be an alternate source of clean, sustainable renewable energy. Moreover, artificial metalloenzymes were designed for solar H2 production using de novo designed metallopeptides. A computer-guided design approach was used to conceive the peptides. These peptides are 30 amino acids long and are designed to self-assemble into tetrameric structures. There are suitably positioned cysteine residues that bind the metal Co and form metallic clusters within these artificial proteins. The Co-metallopeptides were then characterized by employing …
