Towards Building New Zeolites with Machine Learning — •Benjamin A. Helfrecht1, Rocio Semino1, 2, Giovanni Pireddu1, 3, Scott M.

Synthesizing new zeolites, which are useful for applications like gas separation and catalysis, with specific properties is an ongoing challenge in the zeolite community. Ideally, one would like to select a handful of compatible “building blocks” from which a new zeolite with desired properties can be synthesized. In this work, we make progress toward this goal by constructing an “atlas” of local atomic environments comprising several thousand all-silica zeolites from the Deem SLC PCOD database [1] using machine learning techniques. We evaluate the utility of this atlas by examining correlations between the locations of the atomic environments in the atlas and their energy and volume contributions to their parent frameworks.
