Heteroatom-substituted microporous AFI and ATS structured materials for hydrocarbon trap:: An insight into the aluminophosphate framework-toluene interaction

We report the synthesis of different heteroatom-substituted aluminophosphates with AFI and ATS topology and their ability to store toluene in wet and dry conditions. By mixing Zeolite A with the material to be tested, it was possible to obtain identical results in both wet and dry conditions. Molecular dynamics simulations coupled with high-resolution X-ray powder diffraction studies allowed us to obtain detailed information on the toluene-framework interactions.
