For the first time, a simple yet efficient water-assisted one-pot pyrolysis (WAOP) strategy was developed to in situ liberate the inaccessible Ru active sites confined inside N-doped carbon. The liberated Ru/CN catalysts exhibit a 9-fold improvement in catalytic activity for quinoline hydrogenation compared with catalysts obtained from the water-free pyrolysis process, and high tolerance for selective hydrogenation of various quinolines substituted with different functional groups. We anticipate that WAOP addresses a key issue that currently plagues carbon-based catalyst synthesis and should lead to improvements in fields as diverse as chemical production and environmental protection.

水辅助一锅法合成N掺杂碳负载的Ru催化剂用于非均相催化。

首次开发了一种简单而有效的水辅助单锅热解（WAOP）策略，以原位释放限制在N掺杂碳内部的不可访问的Ru活性位。与从无水热解方法获得的催化剂相比，释放的Ru / CN催化剂对喹啉加氢的催化活性提高了9倍，并且对不同官能团取代的各种喹啉的选择性加氢具有较高的耐受性。我们希望WAOP解决当前困扰碳基催化剂合成的一个关键问题，并将导致化学生产和环境保护等各个领域的改进。
