Spatially decoupling bromide-mediated process boosts propylene oxide electrosynthesis

https://phys.org/news/2024-07-spatially-decoupling-bromide-boosts-propylene.html

"bromide reaction spatially decouples electrolysis/ propylene conversion, in propylene's electrocatalytic oxidation, producing propylene oxide... Br2 produced at anode then transferred to independent reactor, reacting with propylene, even at high currents... inexpensive carbon paper anode... >99.9% selectivity under all applied potentials... 91% faradaic efficiency at 1.9 V, stable >30 days at 250 mAcm-2 current density with only 0.73% faradaic efficiency decay... electrolysis for 50 h, 6.25 A, produced 262 g propylene oxide"
