What is Abinit?
Abinit is a software suite that allows for the calculation of the optical, mechanical, vibrational, and other observable properties of materials using quantum mechanics. It is particularly useful for researchers in the field of
catalysis to model and understand the behavior of catalysts at the atomic level.
Why is Abinit Important in Catalysis?
Understanding the atomic and electronic structure of catalysts is crucial for designing more effective and efficient catalytic processes. Abinit provides a framework for performing
density functional theory (DFT) calculations, which are essential for predicting how catalysts interact with reactants. These calculations can help in identifying active sites, understanding reaction mechanisms, and optimizing catalytic materials.
