“…106 Cobalamin, or vitamin B12 (VB12), can be used for the dechlorination of trichloroacetic acid to produce acetic acid in a 93% at a j of −7 mA cm −2 under 5 h, with dichloroacetic acid and monochloroacetic acid as minor byproducts. 107 Similarly, VB12 can also debrominate tribromoacetic acid with 99% of FE after 6 h under optimal galvanostatic conditions ( j = −10.0 mA cm −2 ). In situ Raman spectroscopy shows Co–Br bond formation, which significantly enhances the electron transfer due to is the main step to initiate the debromination process.…”
