This data repository entry contains the following original data files that support the journal article "SAXS for Extracting Pore Size Distributions of Rare-earth-doped Ceria-Zirconia Oxygen Storage Catalysts".

SAXS and Nitrogen adsorption data in text/dat format.

The naming scheme is "aa_bb_cc_dd".txt/dat, where aa is the average pore size by nitrogen adsorption in angstroms, bb is the average pore size by SAXS in angstroms, cc is the composition and dd is either "isotherm" or "psd" for the nitrogen adsorption data. "isotherm" is the nitrogen adsorption isotherm and "psd" is the pore size distribution obtained from the nitrogen adsorption data using the BJH method on the adsorption branch.
