Metal‐Organic‐Framework‐Derived Hollow N‐Doped Porous Carbon with Ultrahigh Concentrations of Single Zn Atoms for Efficient Carbon Dioxide Conversion

The development of efficient and low energy‐consumption catalysts for CO2 conversion is desired yet remains a great challenge. Herein, a class of novel hollow porous carbons (HPC), featuring well dispersed dopants of nitrogen and single Zn atoms, have been fabricated, based on the templated growth of hollow metal‐organic framework precursor followed by pyrolysis. The optimized HPC‐800 achieves efficient catalytic CO2 cycloaddition with epoxides under light irradiation at ambient temperature, by taking advantage of an ultrahigh loading of (11.3 wt%) single‐atom Zn and uniform N active sites, high‐efficiency photothermal conversion as well as the hierarchical pores in the carbon shell. As far as we know, this is not only the first work employing single atoms but also an unprecedented study harnessing photothermal effect of carbon‐based materials for enhanced catalytic CO2 conversion.
