These slides provide a brief introduction to the concept of electrocatalysis using the glyoximato cobalt catalysts for hydrogen production recently examined by Peters, Gray, and others. They provide a suitable introduction to the topic for students interested in reading the primary literature on these topics.
- A student should be able to define what an electrocatalyst is and the general mechanism by which an electrocatalyst operates.
- A student should be able to identify a cyclic voltammetric trace corresponding to an operating electrocatalyst and explain why it is different from the electrochemistry of the same complex in the absence of substrate.
- A student should be able to identify the important features in evaluating the efficiency of an electrocatalyst and define the term "overpotential".
This set of slides is recommended as background reading (or in-class presentation) for students working on the LO developed from the Valdez et al. PNAS paper "Catalytic hydrogen evolution from a covalently linked dicobaloxime" (the LO is referenced above).
