chatmaterials Catalysis Analysis
Use this skill for catalysis-oriented post-processing rather than generic workflow setup.
When to use
- estimate adsorption energies from slab, adsorbate, and adsorbed calculations
- summarize a simple d-band center from projected DOS data
- estimate reaction barriers from NEB image sets
- rank multiple catalyst candidates in balanced, activity, poisoning-resistant, or descriptor modes
- compare adsorption selectivity between two adsorbates on the same slab
- compare selectivity between competing reaction pathways
- compare adsorption preference across multiple surface sites
- write a compact catalysis-analysis report from existing calculations
Supported backends:
- VASP-like directories with
OUTCAR - QE-like directories with
.out - ABINIT-like directories with
.abo

Guardrails
- Do not overinterpret adsorption energies without stating the reference states.
- Treat a simple d-band center as a descriptor, not a proof of catalytic activity.
- Distinguish reaction barriers from adsorption thermodynamics.
