摘要：

Highly selective synthesis of primary amines from renewable biomass has attracted increasing attention, but it still faces great challenges in chemical industry applications. In this study, an electron-rich Ru catalyst was constructed by doping N into coffee biochar using a one-pot carbonization method (Ru/NCB-600). Ru/NCB-600 showed high catalytic activity and yield for the reductive amination of furfural with green and cheap NH3 and H-2. The excellent catalytic performance of Ru/NCB-600 was closely correlated to the formation of electron-rich Ru delta- species (Ru delta--N-x(delta+)), which endowed Ru/NCB-600 with an enhanced H-2 adsorption and activation ability. Ru/NCB-600 showed a high formation rate of 95.6 g(furfurylamine)<middle dot>g(Ru)(-1)<middle dot>h(-1) and a high yield of furfurylamine (98.6%) at 50 degrees C. Ru/NCB-600 can also be used for the reductive amination of various carbonyl compounds in good to excellent yield (95.4-99%). This study thus provides a potential pathway for the highly selective reductive amination of carbonyl compounds by regulating the electron density of Ru.
