Abstract

Nitrogen modified cobalt catalysts supported on carbon were prepared by pyrolysis of the mixture generated from cobalt(ii) acetate in aqueous solution of melamine or waste melamine resins, which are widely used as industrial polymers. The obtained nanostructured materials catalyze the transfer hydrogenation of N-heteroarenes with formic acid in the absence of base. The optimal Co/Melamine-2@C-700 catalyst exhibits high activity and selectivity for the dehydrogenation of formic acid into molecular hydrogen and carbon dioxide and allows for the reduction of diverse N-heteroarenes including substrates featuring sensitive functional groups.

摘要

通过热解由醋酸钴在三聚氰胺水溶液或废三聚氰胺树脂（广泛用作工业聚合物）中生成的混合物，制备了负载在碳上的氮改性钴催化剂。所获得的纳米结构材料在无碱条件下催化N-杂芳烃与甲酸的转移氢化反应。最佳的Co/Melamine-2@C-700催化剂对甲酸脱氢生成分子氢和二氧化碳表现出高活性和选择性，并能还原多种N-杂芳烃，包括具有敏感官能团的底物。
