An economical and facile method for high-yield production of cobalt and nitrogen co-doped carbon by employing Cobalt salicylate/1,3-dimethylurea though pre-pyrolysis in high pressure is presented. The pre-pyrolysis process helped to produce more carbon, resulting in a weight loss of only 27% after twice pyrolysis. The as-prepared Co@N-doped carbon was charactered and applied as catalyst for the carbonylation of amines to form formamides for the first time in an atomic economic method. A new strategy for synthesis of Co@N-doped carbon materials which is scalable and of high-yield provides highly efficient cost-effective catalyst for economic carbonylation of amines to form formamides.

提出了通过水杨酸钴/ 1,3-二甲基脲尽管在高压下进行预热解而高产钴和氮共掺杂碳的经济，简便方法。预热解过程有助于产生更多的碳，两次热解后的重量损失仅为27％。表征了所制备的Co @ N掺杂的碳，并首次以原子经济方法将其用作胺羰基化形成甲酰胺的催化剂。一种可扩展且高产率的合成Co @ N掺杂碳材料的新策略，为胺的经济羰基化以形成甲酰胺提供了高效的，具有成本效益的催化剂。
