S1 Appendix - Square Wave Voltammetry of TNT at Gold Electrodes Modified with Self-Assembled Monolayers Containing Aromatic Structures

Supporting figures and tables. S1 Fig. Cathodic stripping voltammetry performed in argon-saturated solutions using 0.5 M KOH buffer at a scan rate of 50 mV/s under Ar for C11 (red), OPE (brown) and biphenyl (blue) SAM modified gold electrodes. Coverages of the SAM molecules on the modified gold electrodes were calculated by integrating the desorption peak at −1.31 V vs. Ag/AgCl for C11, for OPE and biphenyl at −1.09 V vs Ag/AgCl. S2 Fig. A. Cyclic voltammograms recorded between 0.2 and −0.2 V vs. Ag/AgCl at a scan rate of 200 mV/s in pH 8 buffer under Ar for C11 (red), OPE (brown) and biphenyl (blue) SAM modified gold electrodes. B. Average of the absolute current at 0 V vs. Ag/AgCl measured from the CVs in A plotted vs. scan rate. Double layer capacitance was calculated from the slope divide by electrode area. S1 Table. Additional parameters used by the DigiElch software. Scan parameters are variables used in the simulation of square wave voltammetry. Experimental conditions refer to standardized parameters of the experiment being simulated. Model parameters are a set of variables relating to the computational simulation, and were left in their default conditions. (DOCX)
