Mapping XANES spectra on structural descriptors of copper oxide clusters using supervised machine learning
Yang Liu,Nicholas Marcella,Janis Timoshenko,Avik Halder,Bing Yang,Lakshmi Kolipaka,Michael J. Pellin,Soenke Seifert,Stefan Vajda,Ping Liu,Anatoly I. Frenkel +10 more
TL;DR: The convolution neural network can be trained on theoretical spectra and utilized to "invert" experimental XANES data to obtain structural descriptors-the Cu-Cu coordination numbers, with important implications for the understanding of structure, composition, and function relationships in catalysis.
Journal ArticleDOI
CO2 Methanation on Cu-Cluster Decorated Zirconia Supports with Different Morphology: A Combined Experimental In Situ GIXANES/GISAXS, Ex Situ XPS and Theoretical DFT Study
