A Molecular Approach to Self-Supported Cobalt-Substituted ZnO Materials as Remarkably Stable Electrocatalysts for Water Oxidation

Hot Paper in Angewandte Chemie by Anna Fischer and Matthias Driess

To be self-made: A cobalt-substituted zinc oxide (Co:ZnO) precatalyst was synthesized by low-temperature solvolysis of molecular heterobimetallic Co_4−xZn_xO₄ (x=1–3) precursors.

Electrophoretic deposition onto fluorinated tin oxide (FTO) electrodes leads, after oxidative conditioning, to an amorphous self-supported water-oxidation electrocatalyst that performs at very low overpotentials and with high current density for several hours.

This paper of Anna Fischer and Matthias Driess has been selected as a hot paper in Angewandte Chemie. Hot Papers are chosen by the Editors of Angewandte Chemie Int. Ed. for their importance in a rapidly evolving field of high current interest.
