EVIDENCE OF A SOLVENT SCREEN EFFECT AFFECTING THE REDOX PROPERTIES OF Co(II) IONS IN CoAPO-37, CoAPO-40 AND CoIST-2 (AEN), BY CYCLIC VOLTAMMETRY

摘要

Cyclic voltammetric experiments of framework Co(II) ions in three different CoAPO structures have provided evidence for a screening effect created by solvent or template molecules which results in a facile oxidation (and a difficult reduction) of the Co(II) ions incorporated into the most open (the less strained) structures. An apparent contradiction of these findings with respect to theoretical expectations is discussed.
