PROX adsorption (Pt)

Introduction

This example is mainly about adsorption of PROX reaction products and intermediate products on the surface of Pt, contributed by the developers of the project.

Inputs

The content of input file is as follow:

StrucInfo:
  struct:
    element: Pt
    lattice_type: fcc
    lattice_constant: 4.16
    facet: ['100']
    dope:
    Cu: ['0']

Model:
  ads:
    - ['OH',1]
    - ['O2',1]
    - ['H2',1]
    - ['H2O',1]
    - ['CO2',1]
    - ['CO',1]
  coads:
    - ['O','H',1,1]

In the directory where the yaml file is located, use the command line to enter htmat ads to generate 27 vasp structure files.

Results

OH adsorption on Pt (100) substrate are construct with 3 configurations!

O2 adsorption on Pt (100) substrate are construct with 3 configurations!

H2 adsorption on Pt (100) substrate are construct with 3 configurations!

H2O adsorption on Pt (100) substrate are construct with 3 configurations!

CO2 adsorption on Pt (100) substrate are construct with 3 configurations!

CO adsorption on Pt (100) substrate are construct with 3 configurations!

O and H adsorption on Pt (100) substrate are construct with 10 configurations!

27 vasp structure files are generated. The visualization results generated by VESTA are as follow:
