Pourbaix Diagram Generator

Welcome to the Pourbaix Diagram Generator (PDG), a Python (3.12.1) tool utilizing the pymatgen (2024.1.26) (A Robust, Open-Source Python Library for Materials Analysis. Computational Materials Science, 2013, 68, 314–319.) package to create Pourbaix diagrams for elements of your choice. This project serves as my initial exploration into pymatgen, making it perfect for those taking their first steps with the package.

The PDG is used in the water electrolysis (PEM/LAWE/AEM) and carbondioxide electroreduction (CO2ER) projects, conducted by the Solar Fuels SF/E4F group (lector: Peter Thüne) at the Fontys University of Applied Science - Applied Natural Science Lectorate (SIA grant for RAAK/PRO - ALMA and RELEASE).

Getting Started

1. Clone the repository:

    git clone https://github.com/kplanken/pourbaix.git
    cd pourbaix
   

2. Install the required packages:

    pip install -r requirements.txt
   

3. Enter element(s) to your liking in main() in main.py

    def main() -> int:
        ...
        compounds: list[str] = [<elements go here>]
        ...
        return 0
   

4. Run the main script to generate Pourbaix diagrams for elements ():

    python main.py
   

Explore the docstrings in main.py for detailed information on available functions.
