摘要：

"Chemical Equation Presented" Biomimetic and efficient: Mixed calcium manganese(III) oxides (see structure; Ca green, Mn red, O white) with elemental compositions and structures mimicking the active site of photosystem II were found to be highly active catalysts for the oxidation of water to molecular oxygen. As for PS II, the presence of Ca2+ greatly enhances the catalyst performance in comparison to the related manganeseonly system Mn2O3. © 2010 Wlley-VCH Verlag GmbH & Co. KGaA.
