Abstract
MnAPO-11 samples were synthesized from aqueous (MnAPO-11(A)) and ethylene g lycol (MnAPO-11(NA)) media. The crystallinity of the samples was more when the synthesis was carried out in ethylene glycol. Chemical and thermogravim etric analyses reveal greater incorporation of Mn in the framework of MnAPO -11(NA) than in MnAPO-11(A). At least five different types of Mn(II) specie s are detected in the samples by ESR. The studies suggest that Mn is more h omogeneously distributed in MnAPO-11(NA) than in MnAPO-11(A).
