| 英文摘要 | Heterogeneous single-atom catalysts (sacs) with atomically dispersed active metal centers represent an intermediary between heterogeneous and homogeneous catalysis. in this work, a porous organic polymer with aminopyridine functionalities was designed to fabricate a stable, atomically dispersed ir catalyst. this ir-based sac exhibits excellent catalytic activity during the liquid-phase hydrogenation of co2 to formate. the associated turnover number is as high as 25,135, representing the best performance yet for a heterogeneous conversion of co2 to formate. spectral characterization and density functional theory modeling demonstrate that the chemical structure of the ir single-atom active site is analogous to that of a homogeneous mononuclear ir pincer complex catalyst. as a result, a catalytic mechanism similar to that over a homogeneous ir catalyst occurs during co2 hydrogenation with this quasi-homogeneous ir-based sac. this work suggests a promising basis for the design of efficient sacs for the once-dominant homogeneous catalytic processes. |
