Congratulations to Deborah and Aderiyike on their recent publication demonstrating the direct electrification of liquid-liquid extraction using a unique redox molecule that combines a ferrocene redox center with a permanently charged ammonium group, enabling ionic conductivity in organic solvents.
This work was recently published in ACS Energy Letters and selected as the supplementary journal cover. The study addresses the fundamental limitations of e-LLE by designing a redox-active extractant that enables direct electrochemical cycling without external redox reagents or added supporting electrolyte. The molecular architecture integrates alkyl chains to tune hydrophobicity, a permanently charged ammonium group to impart ionic conductivity in organic media, and a ferrocene redox center to enable selective and reversible electrochemical extraction. The platform achieved 89% selective gold recovery from electronic waste leachates with a separation factor of 35, while techno-economic analysis demonstrated significant reductions in both capital (CAPEX) and operating (OPEX) costs.
