Co-based MOF derived metal catalysts: from nano-level to atom-level

Co-based metal–organic framework (MOF), a kind of porous crystal material composed of Co ions and organic linkers, is a common type of MOF. It not only has the intrinsic properties of MOF, such as structural diversity, functional adjustability, and high surface area, but more importantly, it contains Co metal species, which are considered by many reports to be active catalytic centers for many reactions. Meanwhile, metal catalysts always received wide and sustained attention. The combination of the two types of catalysts can enhance the catalytic performance and achieve the “1 + 1 > 2” effect. In this review, we mainly overview the synthesis methods of Co-based MOF-derived metal catalysts from nano- to atom- level and their applications in the catalysis field in recent years and put forward our own views and prospects for this research direction.
