core–shell based nanoparticles prepared by template synthesis of cobalt‐pyromellitic acid on silica and subsequent pyrolysis. The optimal catalyst material allows for general and selective hydrogenation of pyridines, quinolines, and other heteroarenes including acridine, phenanthroline, naphthyridine, quinoxaline, imidazo[1,2‐a]pyridine, and indole under comparably mild reaction conditions. In addition
在此,我们报道了通过二氧化硅上钴均苯四酸的模板合成和随后的热解制备的特定二氧化硅负载的Co/Co 3 O 4核壳纳米粒子的合成。最佳的催化剂材料允许在相对温和的反应条件下对吡啶、喹啉和其他杂芳烃(包括吖啶、菲咯啉、萘啶、喹喔啉、咪唑并[1,2-a]吡啶和吲哚)进行全面和选择性氢化。此外,还展示了这些钴纳米颗粒的回收利用及其脱氢催化能力。
