Catalysis and Electrochemistry Toolkit (6 sub-skills: band-center, imaginary-freq-correction, implicit-solvation, neb-analysis, reaction-kinetics, thermal-corrections)
This skill group covers computational catalysis and electrochemistry workflows corresponding to VASPKIT menu 05 (tasks 501-509). It provides tools for computing thermodynamic corrections to DFT energies, analyzing reaction pathways (NEB), extracting d-band descriptors for catalytic activity, and applying transition state theory for reaction kinetics.
| Sub-Skill | Directory | Description |
|---|---|---|
| Thermal Corrections | thermal-corrections/ | Zero-point energy, thermal corrections for adsorbates and gas-phase molecules (VASPKIT 501-502). Uses ASE thermochemistry, ideal gas, and harmonic approximations. |
| NEB Analysis | neb-analysis/ | NEB path analysis, converting NEB paths to PDB trajectories, interpolating NEB images (VASPKIT 504-505). Uses ASE NEB, pymatgen, QE NEB. |
| d-Band Center | band-center/ | d-band center calculation from projected DOS (VASPKIT 503). Parse QE/VASP PDOS data for catalytic activity descriptors. |
| Reaction Kinetics | reaction-kinetics/ | Imaginary frequency correction (VASPKIT 507), half-life calculation (VASPKIT 509). Transition state theory rate constants and kinetic analysis. |
| Implicit Solvation | implicit-solvation/ | Implicit solvation models for electrode-electrolyte interfaces. VASPsol, QE+Environ, and ASE-based Born/GBSA corrections. Solvation free energies, pKa, electrochemical reaction energetics with solvent effects. |
