However, this method suffers from harsh energy demand and reliance on highly toxic hydrogen cyanide, thereby posing significant environmental and safety concerns. Herein, we developed a sustainable electroreforming strategy for ADN synthesis from waste nylon\u201066 using Mn doped Co\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    (Mn\u2010Co\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    ) catalyst.
