Catalytic pathways for the reduction of dioxygen can either lead to the formation of water or peroxide as the reaction product. We demonstrate that the electrocatalytic reduction of O2 by the pyridylalkylamine copper complex [Cu(tmpa)(L)]2+ in a neutral aqueous solution follows a stepwise 4 e−/4 H+ pathway, in which H2O2 is formed as a detectable intermediate and subsequently reduced to H2O in two...
Vor Kurzem wurde eine Reihe einkerniger Wasseroxidationskatalysatoren beschrieben – ein Durchbruch angesichts der Lehrmeinung, dass mindestens zwei Metallzentren für eine effiziente Wasseroxidation erforderlich wären. Dieser Kurzaufsatz bietet einen Überblick über die einkernigen Katalysatoren, die innerhalb der letzten fünf Jahre beschrieben wurden. Vorgestellt wird auch ihr Einsatz in einem Prototyp,...
