For FTIR experiments, we began using a custom Otto Configuration that consisted of a ZnSe ATR crystal onto which we placed an FTO coated glass electrode with our cobalt catalyst face down. This, however, had large background noise and prevented evolved oxygen from escaping. We then switched to the Kretschmann Configuration which utilized a silicon ATR crystal plated with a gold film onto which our catalyst was then deposited. This configuration reduced some of the background noise and allowed oxygen to escape into the electrolyte solution.
