Catalyst structure optimization for the oxygen reduction reaction on Pt and Au

Project description

ORR Optimization

Catalyst structure optimization for the oxygen reduction reaction on Pt and Au.

Dependencies

  • Atomic simualtion environment (3.17.0) <https://wiki.fysik.dtu.dk/ase/>_ : Data structures for molecular structures and file IO.
  • See requirements.txt for suitable virtual environment dependencies
  • Minimum of 8GB of memory recommended

Publications

  • M. Núñez, J. Lansford and D.G Vlachos, “Optimization of the facet structure of transition-metal catalysts applied to the oxygen reduction reaction” Nature Chemistry (2019) <https://www.nature.com/articles/s41557-019-0247-4>_

Developers

Directory Structure

  • orr_optimizer: Core classes for simulating the ORR chemistry and catalyst structure
  • volcano: generate_volcanoes.py produces all_volcanos.npy, which is read by the files in the structures folder.
  • optimization_scripts: Optimize_main.py performs a sample optimization. Extract_data.py shows data from the publication.
  • figures: produces some figures from publication

Usage

  • Add repository to PYTHONPATH environment variable
  • import orr_optimizer or run scripts in the scripts folder
