Perspectives in Computational Catalysis: Data-Driven and Operando Approaches
Popis výsledku v původním jazyce
The Nanomaterials Modelling group at Charles University developed atomistic simulation methods combining machine learning with quantum chemistry to study catalytic materials under realistic conditions and to investigate systems of high industrial relevance. Their work produced transferable reactive interatomic potentials for zeolites and oxide catalysts, accelerated rare-event sampling, and established property predictors linking structural features to spectroscopic signatures. Applications of machine-learning interatomic potentials and regression models included studies of confined water in aluminosilicate zeolites, aluminium siting determined by solid-state NMR, and the stabilisation of sub-nanometre bimetallic noble-metal clusters through alloying, oxidation, and defects. The results showed that machine-learning-driven dynamical modelling uncovered unexpected binding modes, reproduced complex experimental NMR spectra with high fidelity, and provided insight into sintering and oxidation processes, while ongoing research further extended these approaches with improved property predictors, rapid potential construction, uncertainty quantification, and large-scale data analysis pipelines.
