On the possibility of incorporating Mn(II) and Cr(III) in SAPO-34 in the presence of isopropylamine as a template
Abstract
Hydrothermal synthesis of SAPO materials using isopropylamine (i-PrNH2) as the template leads to the formation of MnAPSO-34 if Mn(II) is present. In the presence of Cr(III), the synthesis yields SAPO-34 containing chromium(III), which is not incorporated in the silicoaluminophosphate lattice. Calcination of MnAPSO-34 results in oxidation of Mn(II); the calcinated product can be subsequently reduced back to MnAPSO-34. The MnAPSO-34 material catalyzes dehydration of methanol, and its catalytic activity is higher than that of SAPO-34.
