Samples of the activated microporous aluminophosphate Co-APO-5, featuring ca. 20% of Co3+ cations, when immersed in water evolve molecular oxygen at room temperature in an endothermic process, without the need for either light or a sacrificial reactant. Successive drying of the sample at temperatures around 520 K releases molecular hydrogen, with recovery of the initial conditions. Several hydration–dehydration cycles may be performed without loss of activity, i.e. water is split in a thermal cycle under relatively mild conditions.
