Nanostructured earth abundant metal catalysts that mediate important chemical reactions with high efficiency and selectivity are of great interest. This study introduces a synthesis protocol for nanostructured earth abundant metal catalysts. Three components, an inexpensive metal precursor, an easy to synthesize N/C precursor, and a porous support material undergo pyrolysis to give the catalyst material in a simple, single synthesis step. By applying this catalyst synthesis, a highly active cobalt catalyst for the general and selective hydrogenation of aromatic heterocycles could be generated. The reaction is important with regard to organic synthesis and hydrogen storage. The mild reaction conditions observed for quinolines permit the selective hydrogenation of numerous classes of N-, O- and S-heterocyclic compounds such as: quinoxalines, pyridines, pyrroles, indoles, isoquinoline, aciridine amine, phenanthroline, benzofuranes, and benzothiophenes.
具有高效和选择性的介导重要化学反应的纳米结构地球丰富金属催化剂具有重要意义。本研究介绍了一种纳米结构地球丰富金属催化剂的合成方案。三种成分，一种廉价的金属前体、一种易于合成的 N/C 前体和一种多孔载体材料，在简单的单一合成步骤中经历热解，得到催化剂材料。通过应用这种催化剂合成，可以生成一种用于芳香杂环的普遍和选择性加氢的高活性钴催化剂。该反应对于有机合成和储氢非常重要。对于喹啉观察到的温和反应条件，允许对许多类 N-、O-和 S-杂环化合物进行选择性加氢，例如：喹喔啉、吡啶、吡咯、吲哚、异喹啉、吖啶胺、菲咯啉、苯并呋喃和苯并噻吩。
