Extended Data Fig. 6. Local Environment within the diffusion layer for MesoITO|H2ase.

Extended Data Fig. 6

Simulation of mesoITO|H2ase (20 pmol) in CO2 purged 0.1 M KHCO3 + 0.05 M KCl (pH 6.67) at t = 270s (steady state), demonstrating the local environment changes as a function of distance from the electrode. (a) The pH change with distance from the electrode surface. b) Concentrations of CO2 (solid lines), HCO3 − (dashed lines), CO32- (dash-dot lines) at −0.65 to −0.3 V vs SHE. c) Concentrations of CO2 (orange), HCO3 − (purple), CO32 -(blue) at −0.65 V (solid lines) from simulation and the expected equilibrium concentrations at the simulated solution pH in SI Fig. 5a (dashed).
