This dataset provides the complete replication data supporting the publication “Ammonia Adsorption by Polyacrylonitrile-based Carbon Nanofibers (https://doi.org/10.1021/acs.iecr.6c01147)\". It contains all raw and processed files required to reproduce every figure presented in the manuscript. The data is based on polyacrylonitrile-based carbon nanofiber pellet samples that were carbonized at temperatures of 800, 850, 900, 950 and 1000 °C. The dataset includes measurements by Scanning Electron Microscopy (SEM), X-Ray Photoelectron Spectroscopy (XPS) and CHNO Elemental analysis. Gas Adsorption Isotherms of Ar and CO2 were measured for general pore characterization and Monte Carlo Simulations were performed to provide Pore Size Distribution. Ammonia adsorption/desorption isotherms and adsorption equilibration curves were measured at 25 and 50 °C.
