The effects of solvents (n-hexane, isopropanol (IPA), tetrahydrofuran (THF) and methanol) on the hydrogenation toluene over Pd/SiO2 Ru/SiO2 catalysts were studied. Microcalorimetric adsorption IR spectroscopy employed to understand effects. It was found that n-hexane adsorbed weakly thus affected less toluene, while THF methanol strongly inhibited activity significantly. IPA also catalysts, but it exhibited a hydrogen transfer effect surfaces promoted conversion toluene.
Pd–Ru/SiO<sub>2</sub> showed special surface chemical properties that were totally different from those of Pd/SiO<sub>2</sub> and Ru/SiO<sub>2</sub> exhibited high activity selectivity for the hydrogenation benzoic acid to cyclohexanecarboxylic acid.
Highly dispersed and loaded (60 wt %) catalysts Co/MgAlO, Co/MgO, Co/Al2O3 were prepared for the hydrogenation of toluene without with triethylamine (TEA). It was found that while Al2O3 favored dispersion Co, MgO promoted reduction CoOx so Co/MgAlO exhibited small Co particles (∼6.5 nm), high H2 uptake (363 μmol/g), thus highly active reaction TEA (not only higher than Co/MgO but also 60% Ni/MgAlO). In addition, adsorption heat significantly lower on Ni/MgAlO activity less affected by...
Highly loaded and dispersed catalysts 60%Ni/Al2O3, 60%Ni/MgO, 60%Ni/MgAlO were used to study the effect of monoethylamine (MEA), diethylamine (DEA), triethylamine (TEA) on hydrogenation toluene. It was found that heats coverages for adsorption toluene hydrogen decreased greatly after preadsorption an ethylamine, thus existence ethylamines inhibited significantly conversion Ni. However, such weakened over Ni supported basic supports (MgAlO MgO). In addition, all three strongly adsorbed Ni,...
Ru/MgO-Al2O3 catalysts (2-6 wt% Ru) were prepared by a two-step co-precipitation method and found to be highly active selective for the hydrogenation of aromatic amines alicyclic amines. Hydrogenation toluene in presence triethylamine (TEA) was used as probe reaction explain obtained results. It that adsorption TEA on Ru than Co Ni significantly less inhibited thus conversion toluene. superior Ni/MgO-Al2O3 Co/MgO-Al2O3
High-surface-area supports SiO2, MgO, and MgSiO (MgO–SiO2) were prepared used to support 2% Pd for the hydrogenation of imines. It was found that basic surface catalysts constrained decomposition diisopropylimine (DIPI), resulting in higher selectivity diisopropylamine (DIPA) during DIPI. However, also limited conversion DIPI over Pd. On other hand, Pd/MgSiO possessed basicity not strong enough so catalyst remained highly active imines, especially production N-methylglucosamine (NMGA) from...
Protein adsorption onto solid surfaces is an immanent and spontaneous phenomenon that occurs in many fundamental biomedical applications. Recent researches mainly focus on collectively measured protein behaviors confined localized nano-sensing areas but ignore the ambient aqueous variation directly affecting behavior, such as hydrogen bonding network protein-water serving a crucial mutually constrained environment. Herein, we develop novel dual-phase plasmonic sensing platform with gold...
Highly dispersed Ru/MgAlO catalysts (2-6%wt) were prepared by a two-step co-precipitation method, which found to be highly active and selective for the hydrogenation of aromatic amines alicyclic amines. Hydrogenation toluene with triethylamine (TEA) was used as probe reaction explain results. It that adsorption significantly less inhibited thus conversion affected, TEA on Ru than Co Ni catalysts. Thus, superior Ni/MgAlO Co/MgAlO
