The oxygen evolution reaction is the thermodynamically and kinetically limiting half of the overall water splitting reaction. To find catalysts that can efficiently and stabley evolve oxygen from water, it is necessary to first understand the mechanism by which water oxidtation happens. In our lab, we study Ni-based catalysts which are highly efficient in an alkaline environment. In particular, we use several in-situ spectroscopy techniques that can show us the structural, electronic, and optical properties of the catalyst during electrochemical cycling.
