To Every Rule There is an Exception: A Rational Extension of Loewenstein's Rule

Artikel i vetenskaplig tidskrift, 2021

Loewenstein's rule, which states that Al−O−Al motifs are energetically unstable, is fundamental to the understanding and design of zeolites. Here, using a combination of electronic structure calculations and lattice models, we show under which circumstances this rule becomes invalid and how it can be rationally extended using the chabasite framework for demonstration.
