Isomorphous Substitution of Framework Atoms by Titanium in VPI-5 Aluminophosphate Molecular Sieve

摘要

Extra-large pore aluminophosphate molecular sieve TiVPI-5 was synthesised hydrothermally in the presence of di- n -butylamine and transformed by the calcination process at 500 °C to a large pore TAPO-8. Incorporation of titanium(IV)...
