A new As3+-silicate molecular sieve with MFI structure
Abstract
New arsenosilicate molecular sieves with MFI topology ([As3+]MFI) efficiently crystallise at relatively low temperature (ca. 85 °C) in 1–2 days (faster than the As-free pure silicalite-1) and exhibit an increased unit cell volume, significant ion-exchange capacity and catalytic activity in acid catalysed n-hexane cracking.
