Fig. 3: Deep H2S oxidation via in-situ generated H2O2 at cathode in H-cell.
From: Electrochemical valorization of H2S in natural gas to sulfate under mild conditions
a Schematic illustration of the electrochemical setup for EChem-SOR in H-cell separated by a bipolar membrane (BPM). H2Scap conversion (b), productivity of oxidation products (c), SO42− selectivity (d), and e−-to-sulfate efficiency (e) for CNT and OCNT without electrolysis or at different applied potentials, with feeding 5% H2S/Ar at a flow rate of 20 ml min−1 for 2 h. The error bars represent the standard deviation of three independent measurements.
