In this study, Al₂O₃/nitrogen-doped carbon supported cobalt catalysts (Co–NC/Al₂O₃-T, where T represents the pyrolysis temperature) were successfully prepared by a one-step pyrolysis method and studied for the hydrodeoxygenation of sulfoxides into sulfides. The structure of the Co–NC/Al₂O₃-T catalysts was greatly affected by the pyrolysis temperature, and thus the pyrolysis temperature showed a great influence on the catalytic activity of the Co–NC/Al₂O₃-T catalysts. The Co–NC/Al₂O₃-500 catalyst demonstrated excellent catalytic performance for the hydrodeoxygenation of sulfoxides into sulfides with yields from 94% to 98% under mild conditions (80 °C and 10 bar H₂), and the catalytic activity of Co–NC/Al₂O₃-500 was found to be comparable with that of reported noble metal catalysts. Both the support and the metallic cobalt nanoparticles crucially contributed to the excellent catalytic activity of the Co–NC/Al₂O₃-500 catalyst. More importantly, the Co–NC/Al₂O₃-500 catalyst showed a good stability after five runs.

在非均相钴催化剂上在温和条件下将亚砜加氢脱氧为硫化物

在本研究中，通过一步热解法成功制备了Al ₂ O ₃ /氮掺杂碳负载钴催化剂（Co-NC/Al ₂ O ₃ - T，其中T表示热解温度）并研究了加氢脱氧亚砜转化为硫化物。Co-NC/Al ₂ O ₃ - T催化剂的结构受热解温度的影响很大，因此热解温度对Co-NC/Al ₂ O ₃ - T催化剂的催化活性有很大影响。Co-NC/Al ₂ O ₃-500 催化剂在温和条件下（80 °C 和 10 bar H ₂）对亚砜加氢脱氧为硫化物表现出优异的催化性能，产率从 94% 到 98% ，以及 Co-NC/Al ₂ O ₃ -发现 500 与报道的贵金属催化剂相当。载体和金属钴纳米粒子都对 Co-NC/Al ₂ O ₃ -500 催化剂的优异催化活性做出了至关重要的贡献。更重要的是，Co-NC/Al ₂ O ₃ -500 催化剂在五次运行后表现出良好的稳定性。
