how train a reaction by MLFF in vasp

Hi,
I can train a MLFF to investigate the structure and its evolution in hundrads of ps time.
I wonder such strategy can be used to train a reaction, for example the CO2 reduction on Cu surface?
Or like QM/MM to provide the solvation environment to hold on the reactants/
I will appreciate your any suggetions and instruction.

Yours

You will need some kind of advanced molecular dynamics method coupled to the machine learning force fields to tackle chemical reactions. In the last VASP workshop in November 2024 these topics were discussed. The talks from the workshop are not available online at the moment but will probably made available online in the future.

We also still have no publication that fully simulates chemical reactions but we are working on it. The closest thing to that was within this publication.
