The HPCvsCO2 project proposes a protocol to accelerate the discovery of new catalysts for the CO2 capture, addressing the computational resource limitations of traditional quantum chemistry methods. The core idea is to integrate Machine Learning (ML) techniques with computational chemistry to predict chemical properties, specifically the HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital) energy, drastically reducing the need to screen vast numbers of molecular configurations computationally. Furthermore, the project investigates the use of Genenerative AI (GenAI) to boost the performance of the ML algorithms within the workflow and generate molecules with a target structure. As part of the HPCvsCO2 project, two datasets of metal-centered catalyst complexes were produced: - The first dataset was used to train and test the UniMol machine learning model for predicting HOMO/LUMO values. - The second dataset was used for fine-tuning the REINVENT4 generative model for generating structurally valid complexes for the project.
