Automated Descriptor Selection, Volcano Curve Generation, and Active Site Determination Using the DescMAP Software

The Descriptor-Based Microkinetic Analysis Package (DescMAP) is a Python library developed by the Vlachos Research Group at the University of Delaware. This code was developed to automate descriptor selection and volcano curve generation for heterogeneous catalysis using empirical and semi-empirical approaches coupled with microkinetic modeling. Both electronic and geometric descriptors are supported. Inputting data via spreadsheets and controlling program behavior via template files increases flexibility and supported capabilities.
