Green and selective hydrogenation of aromatic diamines over the nanosheet Ru/g-C3N4-H2 catalyst prepared by ultrasonic assisted impregnation-deposition method
文献摘要：
In this study,nanosheet g-C3N4-H2 was prepared by thermal exfoliation of bulk g-C3N4 under hydrogen.A series of Ru/g-C3N4-H2 catalysts with Ru species supported on the nanosheet g-C3N4-H2 were synthesized via ultrasonic assisted impregnation-deposition method.Ultrafine Ru nanoparticles(＜2 nm)were highly dispersed on nanosheet g-C3N4-H2.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'-diaminodicyclohexyl methane 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 molRu-1h-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 H2 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.
