A highly stable polypyridyl-based cobalt catalyst for homo- and heterogeneous photocatalytic water reduction

Abstract

Synthesis, characterization and activity in homogeneous photocatalytic hydrogen production of a cobalt polypyridyl complex are reported. TONs up to 9000 H2/Co could be achieved. Immobilization of the complex on a swellable resin yielded a recyclable heterogeneous catalyst. © 2013 The Royal Society of Chemistry.
