原子非贵金属材料在催化领域显示出替代贵金属的潜力。本文开发了三聚氰胺甲醛树脂，用于在介孔掺氮碳表面合成原子铁。含氮量丰富的三嗪单元和空腔可以有效地实现单金属原子的锚定。原子铁具有独特的电荷和配位特性，在脱氢反应中表现出优异的催化性能。各种N-杂环化合物和胺可以在室温下有效地脱氢生成相应的产物，这是所有已报道的反应条件中最温和的，即使考虑到贵金属催化剂。因此，开发具有介孔结构的原子非贵金属催化剂可能为实现多相催化中贵金属的替代提供一条有效的途径。
Atomic non-noble metal materials show the potential to substitute noble metals in catalysis. Herein, melamine formaldehyde resin is developed to synthesize atomic iron on mesoporous nitrogen-doped carbon. The triazine units with abundant nitrogen content and cavity can realize effectively anchoring of single metal atoms. The atomic iron with unique charge and coordination characteristics shows superior catalytic performance in dehydrogenation reaction. Various N-heterocycles compounds and amines can be efficiently dehydrogenated into the corresponding products at room temperature, which is the mildest of all reported reaction conditions even when noble metal catalysts are considered. Therefore, development of atomic non-noble metal catalysts with mesoporous structure may provide an effective way to realize the substitution for noble metals in heterogeneous catalysis.
