I have prepared an electrocatalyst for the Oxygen evolution reaction. But I have no idea regarding the calculation of the Turnover frequency and the Faradic efficiency of the catalyst. Can anyone help me on this regard?
Follow this article, "Benchmarking Heterogeneous Electrocatalysts for the Oxygen Evolution Reaction" J. Am. Chem. Soc., 2013, 135 (45), pp 16977–16987, hopefully you will find your answer.
In short, "the TOF may refer to the rate of electron delivery per surface metal atom per second or the rate of product molecules evolved per surface metal atom, per total
metal atoms including subsurface metal, or per electrochemically active surface site.
