Kinetic isotope effect studies can provide valuable insights into the complex mechanisms of the oxygen reduction reaction; however, inaccessibility to ultra-high-purity D2O has made this difficult. Now, a methodology to prepare ultra-pure D2O has been developed and inverse kinetic isotope effects have subsequently been measured for the oxygen reduction reaction on platinum single-crystal surfaces, providing mechanistic insights.
