英文摘要In this study, nanosheet g-C3N4-H-2 was prepared by thermal exfoliation of bulk g-C3N4 under hydrogen. A series of Ru/g-C3N4-H-2 catalysts with Ru species supported on the nanosheet g-C3N4-H-2 were synthesized via ultrasonic assisted impregnation-deposition method. Ultrafine Ru nanoparticles (< 2 nm) were highly dispersed on nanosheet g-C3N4-H-2. Strong interaction due to Ru-Nx coordination facilitated the uniform distribution of Ru species. Meanwhile, the involvement of surface basicity derived from abundant nitrogen sites was favourable for enhancing the selective hydrogenation performance of bi-benzene ring, i.e., almost complete 4,4'-diaminodiphenylmethane (MDA) conversion and > 99% 4,4'-diaminodicyclohexylmethane selectivity, corresponding to a reaction activity of 35.7 molMDA molRu(-1) h(-1). Moreover, the reaction activity of catalyst in the fifth run was 36.5 molMDA mol(Ru)(-1) h(-1), which was comparable with that of the fresh one. The computational results showed that g-C3N4 as support was favorable for adsorption and dissociation of H-2 molecules. Moreover, the substrate scope can be successfully expanded to a variety of other aromatic diamines. Therefore, this work provides an efficient and green catalyst system for selective hydrogenation of aromatic diamines. (c) 2021 Institute of Process Engineering, Chinese Academy of Sciences.
