Abstract:

Heterogenization of organic-macrocyclic metal catalysts is one of the simplest and most efficient methods for effective separation of products and cyclic application of a catalyst. By using an environmentally friendly Mn-corrolazine catalyst as the building unit, which can directly oxidize organic substrates under oxygen atmosphere and mild conditions, we theoretically constructed a novel two-dimensional (2D) Mn-corrolazine nanocatalytic material with high catalytic activity. In this material, each Mn atom maintains its electronic configuration in the monomer and can directly activate O2 as the single-atom catalyst (SAC) center to form a radical-like [Mn]-O-O under mild visible-light irradiation conditions. The newly generated [Mn]-O-O can efficiently and selectively oxidize C-H bonds to form alcohol species through H-abstraction and the rebound reaction. Moreover, the catalytic reaction is easily regulated by an external electric field along its intrinsic Mn-O-O reaction axis. The current study provides a theoretical foundation for further experimental studies and practical applications of the Mn-corrolazine-based SAC.
