…of zeolite catalysts in order to carry out very specific syntheses of high-value chemicals. Periodic DFT methods permit investigations of properties of zeolite-based catalysts which are needed for their fine-tuning. DFT calculations are complementary to experimental examinations and together they can provide more complex knowledge of the properties of the studied catalysts and the reactions they catalyze.

In this project, we will explore whether density functional theory, which is a much more efficient method typically including empirical parameters, can be used in place of the aforementioned expensive methods to describe 1D and 2D systems. This will be done by applying the concept of nonempirical…
