Abstract Selective hydrogenation and hydrogenolysis of 5‐hydroxymethylfurfural were performed with carbon nanotube‐supported bimetallic NiFe (NiFe/CNT) catalysts. The combination Ni Fe in an appropriate atomic ratio Ni/Fe (2.0) significantly increased the selectivity to 2,5‐furandimethanol or 2,5‐dimethylfuran depending on reaction temperature. selectivities as high 96.1 % at 383 K 91.3 473 K, respectively. characterization results confirmed that particles sizes less than 7 nm formed...
CO 2 hydrogenation coupled with toluene methylation can markedly enhance the production of high value-added para -xylene.
Hexamethylene diamine, an important chemical intermediate for polyamides, can be synthesized through the two-step route of caprolactam (CPL) ammonolysis to 6-aminocapronitrile (ACN), followed by hydrogenation. This method has received increasing attention from academia and industry. However, studies on catalyst structure-performance correlation in CPL are still sporadic. In this work, a series anatase TiO2 with different oxygen vacancy concentrations was prepared reduction using NaBH4. The...
Copper nanoparticles exsoluted in situ under a reducing atmosphere at elevated temperatures are socketed into the parent copper phyllosilicate nanotubes and exhibit excellent catalytic performance superior stability for selective hydrogenation of various esters to alcohols.
Surfactant-free bimetallic Ni@Ag nanoparticles in mesoporous silica, SBA-15 prepared by simple wet co-impregnation catalyse hydrogenation of dimethyl oxalate to methyl glycolate or ethylene glycol high yield.
Deep hydrogenation of polycyclic aromatic hydrocarbons is an important reaction in the petroleum industry. Sintering and coking active metal nanoparticles are major reasons for deactivation. In this study, a Ni phyllosilicate with different morphologies was synthesized by modified hydrothermal method used naphthalene. The physicochemical properties were carefully examined various characterizations. situ exsolution inlaid into strengthens interaction between support, thereby maintaining size...
Several lactam-based Brønsted-acidic ionic liquids with different acidities were synthesized and applied to the esterification of carboxylic acids alcohols. High conversion perfect selectivity obtained under mild conditions. Among investigated, those having a methyl sulfonate anion (which has weaker acidity than tetrafluoroborate anion) afforded highest activity for esterification. The results indicated that immiscibility synergistic effect on their performance. Furthermore, after removal...
A bimetallic nanocatalyst Ru–Fe/SBA-15 shows remarkable ability to catalyze selective hydrogenolysis of carboxylic acids alcoholic chemicals and the optimized catalyst is stable for acetic acid ethanol with high catalytic performance 300 h.
Polyvinylpyrrolidone-stabilized heteropolyacids (PVP–HPAs) are synthesized by self-assembling in alcohol. The structure of PVP–HPAs is determined various characteristic techniques. HPAs can protonate PVP to form polymeric cations. In turn, the protonated interacts strongly with heteropolyanion forming an ionic liquid (IL)-like structure. separation and recyclability characteristics related PVP's IL-like catalyzing performance varies species HPA content PVP. optimized PVP–H4SiW12O40·5H2O...

The amination of phenol to aniline is a sustainable method replace the traditional synthesis primary by nitrobenzene–hydrogenation and halobenzene–amination. Under hydrogen atmosphere, supported Pd catalyst exhibits significant activity in with various amines, but selectivity poor. Here, we showed that can be realized using small amount cyclohexanone as an inducer without need for external addition over Pd/MgO catalyst. condition inducer, reach twice under conversion did not significantly...
Durene is a valuable aromatic hydrocarbon used in making polyimide and aviation kerosene additives, which traditionally rely on unsustainable petroleum sources, leading to high costs environmental concerns. Herein, we introduce an alternative method for synthesizing durene with selectivity through trimethylbenzene methylation coupled CO2 hydrogenation. of 83.2% tetramethylbenzene (TetraMB) TetraMB 69.1% aromatics were achieved 1,2,4-trimethylbenzene conversion 33.2%. Remarkably, the remained...
