Karanjit, Sangita published the artcileA heterogeneous bifunctional silica-supported Ag2O/Im+Cl- catalyst for efficient CO2 conversion, Name: 3,5-Dimethylhex-1-yn-3-ol, the main research area is silica silver oxide imidazolium salt catalyst carbon dioxide conversion.

A silica-supported bifunctional heterogeneous catalytic system was developed based on imidazolium salt (Im+Cl-@SiO2) as an activator. The Im+Cl-@SiO2 activated both the Ag-catalyst and substrate for the carboxylative cyclization reaction of alcs. by the efficient utilization of CO2 under ambient conditions. The catalyst is quite stable and versatile and could be stored without the need of a protective atm. We also confirmed the reusability of the catalyst up to five cycles. Our catalytic system performed very well not only for the two-component reaction of propargyl alcs./amines with CO2, but also for the three-component reaction of propargyl alcs., CO2, and other alcs./amines with excellent yields of the corresponding carbonates and carbamates under mild reaction conditions. This system secures the advantages of both homogeneous and heterogeneous catalysis of ammonium salts with good activity, as well as easy isolation of the product and easy recovery of the catalyst.

Du, Cheng published the artcileDirect Surface Modification of Graphitic C3N4 with Porous Organic Polymer and Silver Nanoparticles for Promoting CO2 Conversion, COA of Formula: C8H14O, the main research area is surface graphitic carbon nitride porous organic polymer silver nanoparticle.

The development of novel heterogeneous catalysts for converting CO2 into fine chems. under mild conditions is extremely attractive but challenging. In this study, graphitic carbon nitride modified by porous organic polymer (POP) and highly dispersed Ag nanoparticles (Ag/POP@g-C3N4) was prepared as a highly efficient heterogeneous catalyst for CO2 conversion for the first time. The POP modifying g-C3N4 remarkably increases sp. surface area and nitrogen species (N-H and C=N); as a result, the abundant porous structures together with anchoring sites allow tight immobilization and homogeneous dispersion of Ag nanoparticles. Benefiting from the effective incorporation, Ag/POP@g-C3N4 exhibited superior catalytic performance for the carboxylative cyclization of propargyl alcs. with CO2 under mild conditions. From the perspective of CO2 adsorption and controlled 1H NMR analyses, a plausible synergistic catalytic mechanism was proposed for the adsorption and activation of CO2 in combination with Ag/POP@g-C3N4 and 1,8-diazabicyclo[5.4.0]undec-7-chin (DBU). Constructing a heterogeneous catalyst by surface modification was proposed to efficiently promote green and sustainable conversion of CO2 into fine chems.

Haque, Najirul published the artcileZn(II)-Embedded Nanoporous Covalent Organic Frameworks for Catalytic Conversion of CO2 under Solvent-Free Conditions, Recommanded Product: 3,5-Dimethylhex-1-yn-3-ol, the main research area is zinc embedded nanoporous covalent organic framework catalytic conversion CO2.

Covalent organic frameworks (COFs) have been gaining substantial attention over the past decade due to their developing crystalline porous polymeric nature linked by strong covalent bonds and widespread applications in various fields. Currently, three-dimensional COFs (3D COFs) are engaging the spotlight due to their distinctive porous features, greater surface area, and exceptional performances in comparison with formerly published two-dimensional (2D) frameworks with the AA-stacking layered mode. In this paper, we present, for the first time, a nanoporous 3D-COF-based zinc(II) catalyst (Zn@RIO-1), which shows an efficient pathway for the chem. conversion of carbon dioxide to produce α-alkylidene cyclic carbonates and oxazolidinones from propargylic alcs. The microporous material with a high surface area (312.61 m2/g) facilitates both types of catalytic reactions under atm. CO2 pressure. More importantly, easily recyclable and reusable catalysts produced moderate to high yields of desired carbonates as well as oxazolidinone products under solvent-free conditions. This study emphasizes the capability of nanoporous 3D-COF-based material in the catalysis field, more specifically in the field of CO2 capture and chem. fixation to fine chems. These results pave a spectacular pathway for the chem. fixation of CO2 into α-alkylidene cyclic carbonates and oxazolidinones from propargylic alcs. using 3D-COF as a potential heterogeneous ligand under sustainable conditions (i.e., solvent-free).

Nisar, Jan published the artcileFuel production from waste polystyrene via pyrolysis: Kinetics and products distribution, Product Details of C8H14O, the main research area is kerosene diesel gasoline oil polystyrene pyrolysis kinetic model; Energy and fuels; Kinetics; Polystyrene; Pyrolysis; Waste management.

In the present study polystyrene waste (PS) was collected from a drop off site in a local market and pyrolyzed at heating rates of 5, 10, 15 and 20°C/min and temperature range 40-600°C under nitrogen condition. The apparent activation energy (Ea) and pre-exponential factor (A) were determined using 6 different kinetic methods. Activation energy and pre-exponential factor were found in the range of 82.3 – 202.8 kJmol-1 and 3.5 × 106-7.6 × 1014 min-1 resp. The results demonstrated that the calculated values of Ea and A vary with fraction of conversion, heating rates and the applied model. Moreover, pyrolysis of waste polystyrene was carried out in an indigenously manufactured furnace at temperatures ranging from 340 to 420°C. The composition of liquid and gaseous fractions was determined using gas chromatog.-mass spectrometry. Temperature and reaction time were optimized and the results revealed that temperature of 410°C and exposure time of 70 min are the best conditions for maximum fuel oil production Methane and ethane were found as the main products in the gas phase constituting about 82% of the gaseous fraction. The liquid products composed of broad range of C2 – C15 hydrocarbons depending on the pyrolytic parameters. A comparison of the composition of pyrolysis oil with standard parameters of diesel, gasoline and kerosene oil suggested that pyrolysis oil from polystyrene waste holds great promise for replacing fuel oil.

Kou, Jinfang published the artcilePrecisely controlled Pd nanoclusters confined in porous organic cages for size-dependent catalytic hydrogenation, Formula: C8H14O, the main research area is palladium nanocluster preparation catalytic hydrogenation property.

The precise size-controlled formation of palladium (Pd) nanoclusters with size-dependent catalytic activity was achieved through a cage confinement strategy. In this process, three typical porous organic cages (POCs) with gradually decreasing cavity diameters were used as encapsulation carriers. A series of Pd nanoclusters-based catalysts with corresponding Pd cluster sizes of 0.73, 0.68, and 0.43 nm, resp., was effectively fabricated by confining the Pd nanoclusters in size-adjustable cavities. The obtained Pd@POCs nanocatalysts exhibited excellent crystallinity, high stability, fascinating morphol. characteristics, and superior catalytic hydrogenation performance. Especially, the size-dependent catalytic performance toward hydrogenation of 4-nitrophenol and semi-hydrogenation of alkyne compounds was demonstrated by exptl. results and theor. calculations The prepared Pd(1.71%)@FT-RCC3 catalyst with the smallest Pd cluster size of about 0.43 nm showed the best catalytic performance. This study promotes a better understanding of size-dependent catalysis and provides a new strategy for the fabrication of customized nanocatalysts.
