摘要

Covalently bound Vitamin B12 hexacarboxylic acid [B_(12)(COOH)_6]-poly(L-lysine) [PLL] on graphite electrodes was evaluated for green electrochemical synthesis in a flow cell in microemulsions. Improved film formation procedure gave higher and more active catalyst surface concentration compared to an earlier method. A parallel plate flow reactor containing a catalyst-coated carbon cloth cathode gave 6-fold larger turnover rates compared to a stirred batch reactor, and maintained 100% current efficiency for catalytic conversion of trans-1,2-dibromocyclohexane [DBCH] to cyclohexene.
