Nitrogen-doped cobalt nanoparticles loaded on porous supports were developed for ring-opening carbonylation of propylene oxide. The catalysts were prepared by simply pyrolysis of Co(OAc)₂/phenanthroline and supports. As proved by XPS combined with XRD and TEM characterizations, a higher amount of available Co-N sites were responsible for promoting the carbonylative activity. The selectivity of carbonylated products reached 93 %, which is comparable to previously reported cobalt carbonyl catalysts. The novel type of carbonylative catalyst also could be reused and revealed fine stability due to the continuous generation of active [Co(CO)₄]⁻ species during reaction.

开发了负载在多孔载体上的氮掺杂钴纳米颗粒，用于环氧丙烷的开环羰基化反应。通过简单地热解Co（OAc）₂ /菲咯啉和载体来制备催化剂。XPS结合XRD和TEM表征证明，大量可用的Co-N位点可促进羰基化活性。羰基化产物的选择性达到93％，与先前报道的羰基钴催化剂相当。由于在反应过程中连续生成活性[Co（CO）₄ ] ^-物种，因此新型羰基催化剂也可以重复使用并显示出良好的稳定性。
