Description
Experimental data supporting "Structural Disorder Determines Capacitance in Nanoporous Carbons".
This dataset contains the raw data used to produce the following figures in the manuscript and supplementary information:
- Main text figures 1 - 3.
- SI figures S1 - 32
'README' text files are included in some subfolder containing detailed metadata on the experiment.
The data set contains data supporting “Structural Disorder Determines Capacitance in Nanoporous carbons” with both main text and supporting information data. In detail, the file includes the N2 gas sorption analysis data of 20 studied nanoporous activated carbons, electrochemical performance of the studied carbons in a standard organic electrolyte for supercapacitors 1 M TEABF4 (ACN). In addition, this data set contains the 19F nuclear magnetic resonance (NMR) spectra of studied nanoporous carbons saturated with the corresponding electrolyte 1 M TEABF4 (ACN), together with the relationship between the Δδ values, carbon domain size and capacitive performance. N2 gas physisorption experiments were carried out using a high vacuum physisorption/chemisorption analyser (autosorb iQ from Anton Paar) at 77 K. All electrochemical measurements were conducted in a two-electrode configuration with a Biologic BCS-805 potentiostat. NMR spectroscopy experiments were carried out with a Bruker Avance Neo spectrometer in a Bruker 2.5 mm HX double resonance probe. The pore size distributions of the studied carbons were generated from fitting the N2 gas isotherms with quenched solid density function theory model. The Δδ values were generated through deconvolution of NMR spectra with DMfit. The studied carbon domain size was calculated by Monte Carlo calculations.
