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 a 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 the first report on the integration of the photothermal effect of carbon‐based materials with single metal atoms for catalytic CO₂ fixation.

金属有机框架衍生的中空N掺杂多孔碳，具有超高浓度的单个Zn原子，可实现有效的二氧化碳转化

期望开发用于CO ₂转化的高效且低能耗的催化剂，但仍然是一个巨大的挑战。在此，根据中空金属-有机骨架前体的模板生长，然后进行热解，制造了一类新颖的中空多孔碳（HPC），其特征是氮和单个Zn原子的掺杂剂分布良好。经过优化的HPC-800可实现有效的催化CO ₂通过在超常负载下（11.3 wt％）单原子Zn和均匀的N活性位点，在光照射下，在环境温度下与环氧化物进行环加成反应，实现高效的光热转化以及碳壳中的分层孔。据我们所知，这是关于碳基材料与单一金属原子用于催化CO ₂固定的光热效应整合的第一份报告。
