  • To introduce an improved surface extraction method for more accurate binding site atom retrieval.

Main Methods:

  • Developed a novel benchmarking criterion using binding site information.
  • Introduced a new surface extraction method employing a rotating cylinder probe.
  • Adapted principles from Weisel et al. (2007) for surface probe methodology.

Main Results:

  • The new benchmarking criteria provide a robust evaluation of surface extraction methods.
  • The proposed rotating cylinder probe method significantly improves binding site atom retrieval.
  • Demonstrated superior performance of the new method over existing surface extraction techniques.

Conclusions:

  • Current surface extraction methods are insufficient for comprehensive binding site identification.
