摘要：

Cobalt-containing aluminophosphate five (CoAPO-5) was synthesized and shown to contain tetrahedral Co2+ residing within framework atomic positions and also as extraframework cations. The isolated framework Co2+ atoms can be oxidized by O2 at 500°C to Co3+ which is stabilized in tetrahedral coordination by the oxide lattice. The framework Co3+ is easily reduced to Co2+ by a variety of reducing agents. © 1990 American Chemical Society.
