摘要

We propose a model for the water-oxidation and recovery systems of the oxygen-evolving complex (OEC) of the photosystem II (PSII) enzyme. The whole system is constructed from two catalytic cycles, conducted as a tandem reaction: (i) a water-oxidation loop uses cerium(IV) ammonium nitrate as an oxidant to activate a dimanganese complex for water-oxidation and thereby liberate a molecule of O_2 and (ii) a recovery loop begins with photoinhibition of the dimanganese complex but then uses O_2 to reactivate the manganese centre. The net result is a catalytic water-oxidation catalyst that can use selfgenerated O_2 for recovery.
