Abstract

Polyethylene glycol supported potassium hydroxide (KOH/PEG1000) was developed as a recyclable catalyst for facile synthesis of urea derivatives from amines and CO2 without utilization of additional dehydrating agents. Primary aliphatic amines, secondary aliphatic amines, and diamines can be converted into the corresponding urea derivatives in moderate yields. Furthermore, the catalyst can be recovered after a simple separation procedure, and reused over 5 times with retention of high activity.

Carbon dioxide hydrogenation to methanol over polybenzoxazine-based mesocarbon supported Cu-Zn catalyst

Varisara Deerattrakul, Anurak Chukchuan, Nattanida Thepphankulngarm, Jirayu Pornjaturawit, Napas Vacharameteevoranun, Thanyalak Chaisuwan, Paisan Kongkachuichay

Summary: The carbon material synthesized from polybenzoxazine, known as mesocarbon, exhibited excellent catalytic properties in direct methanol synthesis from CO2 hydrogenation. The high catalytic activity is attributed to the high surface area and nitrogen content of mesocarbon, which can prevent metal agglomeration and enhance hydrogen dissociation.

Thermomorphic Polyethylene-Supported Organocatalysts for the Valorization of Vegetable Oils and CO2

Ayman Akhdar, Killian Onida, Nam Duc Vu, Kevin Grollier, Sebastien Norsic, Christophe Boisson, Franck D'Agosto, Nicolas Duguet

Summary: A range of thermomorphic polyethylene-supported organocatalysts were prepared with good yields and high functionality, and studied for the ring opening of epoxidized methyl oleate with CO2. The optimized conditions were applied to a range of epoxidized fatty acids, showing good yields of the corresponding carbonates. Catalyst recycling study demonstrated no significant loss of activity, making fatty carbonates important intermediates for non-isocyanate polyurethanes (NIPUs) preparation.

Tetraalkylammonium-based dicationic ionic liquids (ILs) for CO2 capture

Prashant S. Kulkarni, Prathamesh Ranjane, Karun Mishra, Swati Sundararajan, Sanjay Kamble

Summary: This investigation presents the synthesis and characterization of a new series of ionic liquids (ILs) for CO2 absorption, aiming to develop more efficient and sustainable technologies. Different ILs were synthesized through modifications and metathesis reactions, and their properties were evaluated using various techniques. The sorption investigation showed that the IL with [BF4]- anion demonstrated the highest CO2 absorption capacity and can be efficiently regenerated and reused. This work highlights the adaptability of tetraalkylammonium-based dicationic ILs for various applications, including sustainable CO2 capture technology.

Ureido Functionalization through Amine-Urea Transamidation under Mild Reaction Conditions

Natalia Guerrero-Alburquerque, Shanyu Zhao, Daniel Rentsch, Matthias M. Koebel, Marco Lattuada, Wim J. Malfait

Summary: Urea, as an alternative to KOCN, shows potential for grafting ureido groups onto amines in aqueous media due to its low cost, non-toxicity, and biocompatibility. Reaction times are almost independent of substrate and pH, but excess urea is required for practically feasible reaction rates.

Facile tailoring of photoluminescence properties of surface-modified TiO2 nanocrystals

Olim Ruzimuradov, Rustam Xasanov, I. Gonzalo-Juan, Dong Fang, Jai Prakash, Ralf Riedel

Summary: This paper reports a novel method of surface modification of TiO2 nanocrystals (NCs) using organic ligands, which can control the optical band gap, generation of trapping states, and inhibiting charge carrier recombination rate. The luminescence properties of TiO2 NCs have been tuned by interacting with ligands such as PEG and FA, leading to efficient visible light-harvesting photocatalytic activity. Furthermore, N-TiO2 NCs with nitrogen doping and functionalization using urea have been synthesized solvothermally at low temperature and high pressure, exhibiting a narrow band gap and slow electron-hole recombination, which can be attributed to surface modification.

Reaction kinetics study of ethylene oligomerization into linear olefins over carbon-supported cobalt catalysts

Alvin Jonathan, Emily G. Tomashek, Michael P. Lanci, James A. Dumesic, George W. Huber

Summary: Ethylene oligomerization over carbon-supported cobalt catalysts at 200 degrees C selectively produces linear olefins and linear alpha olefins, with increasing the catalyst pretreatment temperature enhancing catalytic activity. However, cobalt metal supported on carbon deactivates during the reaction, likely due to higher rate of polyethylene formation, and the product distribution follows a Schulz-Flory distribution. The reaction is first order with respect to ethylene partial pressure, suggesting a mechanism involving the reaction of ethylene with adsorbed olefins on a highly covered surface.

Molecular-level investigation on supported CrOx catalyst for oxidative dehydrogenation of propane with carbon dioxide

Jian Wang, Min-Li Zhu, Yong-Hong Song, Zhao-Tie Liu, Li Wang, Zhong-Wen Liu

Summary: In this study, the catalytic performance of CrOx catalyst dispersed on dealuminated b zeolite was investigated using the oxidative dehydrogenation of propane with carbon dioxide as a probe reaction. The results revealed that the dispersion of Cr species and the content of initial highly-dispersed Cr6+ oxides played a crucial role in the activity of the catalyst. The researchers discovered that the oxygen from terminal Cr = O bonds in initial Cr6+ oxides reacted with propane molecules, generating coordinatively unsaturated Cr3+ oxides as active sites for the redox cycles of CO2-ODP.
