Water-assisted one-pot synthesis of N-doped carbon supported Ru catalysts for heterogeneous catalysis

摘要

For the first time, a simple yet efficient water-assisted one-pot pyrolysis (WAOP) strategy was developed toin situliberate 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.
