Nanostructured catalysts for low-temperature ammonia synthesis have been developed via thermal treatment under nitrogen of Ru-containing MOFs. The resulting catalysts reveal high concentration of small Ru nanocrystals (<4 nm) well-dispersed on a graphitic carbon shell demonstrating stable ammonia formation rates at low temperature. Additional acetylene pre-treatment leads to more dispersed active catalysts containing stable sub-nanometric Ru clusters.

MOF衍生的用于低温氨合成的纳米结构催化剂

通过在含Ru的MOF的氮气氛下进行热处理，开发了用于低温氨合成的纳米结构催化剂。所得催化剂显示出高浓度的细小Ru纳米晶体（<4 nm）很好地分散在石墨碳壳上，表明在低温下稳定的氨形成速率。额外的乙炔预处理会导致分散的活性催化剂包含稳定的亚纳米Ru团簇。
