Hydrogen spillover has provided great insights for elevating catalytic performance in hydrogen-involved heterogeneous processes, which is normally promoted by the reducible oxide support. However, it seems powerless some cases when unreducible desired to play role activating another molecular reactant, and thus competition needs be reconciled. Herein, taking tandem reductive amination of furfural as an example, we constructed Ru/Ga2O3/MgAlGaOx catalyst, metallic Ru sites Al3+ take responsibility H2 dissociation intermediate Schiff base activation, respectively. More attractively, nanosized Ga2O3 atomic distributed Ga3+ MgAlGaOx can considered dual scale hydrogen transfer bridges break deadlock. As dissociated H* efficient site timely, facilitating vital step hydrogenolysis furfurylamine, as-synthesized catalysts achieved satisfactory performance, universality, cycling stability (93% yield, 80.43 gFAM·gRu–1·h–1 product formation rate, broad scope 14 substrates, recycling 5 times) under both mild pressure extremely low NH3 feeding conditions. Through designed in/ex-situ experiments DFT calculations, such a promotional effect was revealed. This work opens strategy avenue other complex reactions presents prospective catalyst biomass upgrading condition.

Bio-based furanic oxygenates represent a well-known class of lignocellulosic biomass-derived platform molecules. In the presence H2 and different nitrogen sources, these versatile building blocks can be transformed into valuable amine compounds via reductive amination or hydrogen-borrowing mechanisms, yet they still face many challenges due to co-existence side-reactions, such as direct hydrogenation, polymerization cyclization. Hence, catalysts with specific structures functions are required achieve satisfactory yields target amines. recent years, heterogeneous catalytic synthesis amines from bio-based has received extensive attention. this review, we summarize discuss significant progress in generation useful sources over catalysts, according various raw materials reaction pathways. The key factors affecting performances, active metals, supports, promoters, solvents conditions, well possible routes mechanisms studied discussed depth. Special attention is paid structure–activity relationship, which would helpful for development more efficient stable catalysts. Moreover, future research direction trend prospected.

Abstract Phenol amination to various valuable amines has attracted considerable attention in heterogeneous catalysis, but limited studies have focused on non‐noble metal catalysts. This study reports a bifunctional catalyst (Ni/SiO 2 ‐AE) containing nickel nanoparticles and Lewis acid sites derived from phyllosilicates for efficient of phenol cyclohexylamine. The Ni/SiO ‐AE resulted 89.4% conversion 86.0% selectivity cyclohexylamine at 160 °C h, which outperforms the catalysts by conventional deposition‐precipitation ‐DP) wetness‐impregnation ‐WI). turnover frequencies based actual exposed surface area ‐AE, ‐DP, ‐WI are calculated as 71.7, 49.0, 8.7 h −1 , respectively. Results demonstrate that Ni exsoluted participate activation dihydrogen molecules, stemmed coordination unsaturated 2+ serve adsorb activate phenol. synergistic effect dual‐functions intensifies amination.
