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. In Recent Advances in the Science and Technology of Zeolites and Related Materials Part B. Proceedings of the 14 International Zeolite Conference, 1649-1654, ISBN: 9780444518262. Amsterdam: Elsevier, 2004.9780444518262AUT: JLO01215;http://hdl.handle.net/10400.1/1256Cyclic 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.engCo incorporationSynthesisconference object2012-06-14
