The principle of microscopic reversibility teaches that the same catalyst catalyzes a reaction in both the forward and reverse directions. Inspired by the multi-copper catalysts employed by nature for the activation of O2 (to form H2O), researchers have been tuning some copper complexes toward water oxidation (to form O2). The electronic structure of the tri-nuclear and hexanuclear complexes has been probed by spectroelectrochemistry and theoretical calculations.

The ultimate goal of this project is to lower the redox potential required for water oxidation to a level that can be achieved by a photovoltaic cell. This will allow the use of abundant water as the source of hydrogen gas for use in hydrogen-fuel cells powering motor cars, ships, appliances, and other devices.

About the Lecture Series
