(A) For different DMSO ratios of PEDOT-PSS-DMSO electrodes, the scan rate is 10 mV s−1 (current normalized with the geometric surface area). (B) Tafel plot of PEDOT-PSS-DMSO. (C) Rate constant of HET vs. the conductivity of PEDOT-PSS electrodes. (The dashed line demonstrated the trend in the exchange current density with respect to the conductivity.)‏ Kosala Wijeratne et al. PNAS 2018;115:47:11899-11904 ©2018 by National Academy of Sciences
