Modeling of boron substitution in zeolites and implications on lattice parameters

Autor: Francesco Di Renzo, Gabriele Valerio, J. Plévert, Annick Goursot

Publikováno v: Physical Chemistry Chemical Physics. 2:1091-1094

The effect of substituting a silicon center with boron in the framework of zeolites has been studied using quantum chemical (QM) calculations on model clusters with formula R3SiOBMR3 (M=H, Na; R=OSiH3). Boron substitution has then been compared with
