Fig. 5: Simulations of the GEOR process with the PE protocol.
From: Pulse potential mediated selectivity for the electrocatalytic oxidation of glycerol to glyceric acid
a Effect of applied constant potential on the diffusion of C2H5O2COO− on the electrode surface. b Surface concentration of GLAD at different electrolysis times for CE and PE protocol (PE1 − PE5: EH = 0.7 VRHE for 0.05 s, EL = 0.3 VRHE for 2.0, 1.0, 0.5, 0.2 and 0.05 s, respectively). c Snapshots of GLA at different electrolysis times for the PE3 protocol. a, b, c Data obtained through COMSOL multiple physical quantities. The catalyst of Pt@G is represented by seven round white dots. d Schematic of the pathways of PE-based GEOR. GLY glycerol, GLAD glyceraldehyde, GLA glyceric acid, TA tartronic acid, GA glycolic acid.
