a The current retention rate of CE and PE protocol with different potentials after 4000 s electrolysis. Product distribution and conversion rate of GEOR under the electrolytic modes of (b) CE and (c) PE (EL = 0.3 VRHE for 0.5 s and EH = 0.6–1.1 VRHE for 0.5 s). The electrolytic charge of different electrolytic modes is basically kept at about 20 C. d Condition optimization of tEL and tEH (EL = 0.3 VRHE, EH = 0.7 VRHE, 50 mM GLY in 1 M KOH) with the selectivity of GLA and the electrolysis time is 1 h. 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. e Selectivity and GLY conversion rate with 20 mM GLY under the electrolytic mode of PE3. The percentages in black indicate the corresponding selectivity of GLA. f Comparison of the GLA selectivity and GLY conversion rate (Data derived from Fig. 2e) in this work with those of previous reports and the numbers in parentheses in the figure indicate the corresponding reference numbers. b, c, d, e TA tartronic acid, GLA glyceric acid, LA lactic acid, OA oxalic acid, GA glycolic acid, FA formic acid.
