Copper Complexes for Water Oxidation

Senior Investigators: Prof. Karen Goldberg (U. Wash.), Prof. Jim Mayer (U. Wash.).

Molecular oxygen, O2, is the greenest, most abundant and inexpensive oxidant imaginable. Conversely, efficient oxidation of water to O2 is a logical, green source of electrons needed for production of fuels and is the most challenging catalytic aspect of the conversion of solar energy to fuels (artificial photosynthesis). CENTC is working to develop and understand homogeneous electrocatalysts based on earth-abundant first-row transition metals, particularly based on biomimetic copper chemistry. We have discovered that copper(II) bis(mu-hydroxo) complexes with bipyridine ligands are promising catalysts for the electrocatalytic oxidation of water.
