Lu, Zijie published the artcileElaboration of microporous CeO₂ thin layers having nanocrystallites network controlled by Pluronic P123: Impact of key experimental parameters, Related Products of ethers-buliding-blocks, the publication is Journal of Sol-Gel Science and Technology (2020), 94(1), 174-185, database is CAplus.

Thus, a compromise between the crystallization and the preservation of the porosity needs to be found. This loss of nanocrystallites organization is more drastic in the direction perpendicular to the surface and less pronounced along the surface. Finally, an increase of the thermal treatment temperature from 300 to 1000°C leads to the formation of fluorite-like dioxide material coupled with a loss of nanocrystallites organization and porosity due to the increase of the size of the crystallites. The results show that the organization of the nanoparticles is possible for a sol ageing time lower than 16 days and that the size of the mesophase within the thin layer increases with the relative humidity fixed during the film deposition. The impact of key exptl. parameters, i.e., the sol ageing, the relative humidity (RH), the thermal treatment, on the thin layer elaboration were investigated. Microporous ceria thin films having nanocrystallites network were synthesized by evaporation-induced self-assembly process, using P123 amphiphilic copolymer as structure-directing agent.

Manjunathan, Pandian published the artcileExploring tailor-made Bronsted acid sites in mesopores of tin oxide catalyst for β-alkoxy alcohol and amino alcohol syntheses, Recommanded Product: 2-Methoxypropan-1-ol, the publication is Scientific Reports (2021), 11(1), 15718, database is CAplus and MEDLINE.

The generation of Bronsted (Sn-OH) and Lewis (coordinatively unsaturated metal centers) acidic sites on the solid surface is a prime demand for catalytic applications. Mesoporous materials are widely employed as catalysts and supports owing to their different nature of acidic sites. Nevertheless, the procedure adopted to generate acid functionalities in these materials involves tedious steps. Herein, we report the tunable acidic sites containing Bronsted sites with relatively varied acid strength in tin oxide by employing soft template followed by simple thermal treatment at various temperatures The readily accessible active sites, specifically Bronsted acidic sites distributed throughout the tin oxide framework as well as mesoporosity endow them to perform with exceptionally high efficiency for epoxide ring opening reactions with excellent reusability. These features promoted them to surpass stannosilicate catalysts for the epoxide ring opening reactions with alc. as a nucleophile and the study was extended to aminolysis of epoxide with the amine. The existence of relatively greater acid strength and numbers in T-SnO₂-350 catalyst boosts to produce a high amount of desired products over other tin oxide catalysts. The active sites responsible in mesoporous tin oxide for epoxide alcoholysis were studied by poisoning the Bronsted acidic sites in the catalyst using 2,6-lutidine as a probe mol.

Kerdouci, Jamila published the artcilePrediction of rate constants for gas-phase reactions of nitrate radical with organic compounds: A new structure-activity relationship, Name: 2-Methoxypropan-1-ol, the publication is ChemPhysChem (2010), 11(18), 3909-3920, database is CAplus and MEDLINE.

A new structure-activity relationship (SAR), based on parametrization of the mol. structure according to the group-additivity method, is presented. On the basis of existing exptl. data for the degradability of approx. 150 organic compounds by the NO₃ radical, this new SAR is developed to estimate the rate constants for reactions with NO₃ radical. At night, nitrate radicals are the most important oxidant of volatile organic compounds The rate constants for their reactions are therefore essential to the understanding of VOC degradation and atm. modeling. The database used for the SAR development includes most classes of compounds such as alkanes, alkenes (acyclic and cyclic), dienes, terpenes and saturated and unsaturated oxygenated compounds (including alcs., ketones, ethers and esters). The proposed SAR shows good efficiency, as 91% of the rate constants are reproduced within a factor of two. The overall agreement between measured and predicted rate constants is very good for most of the unsaturated and saturated compounds, although for saturated alcs. it is less reliable.

Kerdouci, Jamila published the artcileStructure-activity relationship for the gas-phase reactions of NO₃ radical with organic compounds: Update and extension to aldehydes, Computed Properties of 1589-47-5, the publication is Atmospheric Environment (2014), 363-372, database is CAplus.

In this work is presented an extension and an update of a recently published structure-activity relationship (SAR) for the prediction of rate constants for gas-phase reactions of VOCs with NO₃ radicals (See previous version in Kerdouci et al., 2011). Such predictive tools are very useful to describe the reactivity of organic compounds in atm. models. This SAR is constructed on the group-additivity method and is based on a wide kinetic database for 185 organic compounds In addition to alkanes, alkenes and saturated and unsaturated oxygenated species already included in the first version of this SAR, this extended version comprises now aldehydes and unsaturated aldehydes. Indeed, since then, new kinetic studies have been performed for alkenals which allow the parameterization of this class of compounds In addition, since new rate constants have been measured for unsaturated ethers, the parameterization of this family of compounds has been completed. Finally, this new version of the SAR shows very good predictive capabilities with more than 90% of the exptl. rate coefficients being reproduced within a factor of two.

Zeolitic imidazolate framework (ZIF-8, Zn(2-meIm)₂) and composites based on ZIF-8 and alumina nanofibers (Nafen^TM), i.e. ZIF-8/Nafen, were demonstrated to be efficient heterogeneous catalysts for the reaction of methanol with propylene oxide to produce propylene glycol Me ether (PGME), which is a member of the family of glycol ether solvents used for a wide variety of consumer products and industrial applications. Both the reaction rate and the selectivity toward PGME were found to decrease with increasing crystal size of the ZIF-8 material, which was related to the change in the number of basic sites and their accessibility. The investigation of ZIF-8/Nafen composites revealed the dependence of their catalytic performance on the amount of the ZIF-8 component. In particular, the activity was affected by the crystal size of the ZIF-8 material and the nature of acid-base sites in its framework.

Different bi-functional materials (Pd(Au)@TS-1) based on metallic nanoparticles supported onto active nanocrystalline titanium silicalite (TS-1) zeolites were synthesized, characterized and used as recyclable heterogeneous catalysts for direct propylene oxide production from hydrogen, oxygen and propylene through one-pot two-step consecutive process. These catalysts allowed carrying out the combined reaction where metallic nanoparticles catalyzed the formation of in situ H₂O₂ that was the necessary intermediate for propylene epoxidation catalyzed by active TS-1 nanocrystalline support. Several variables were considered such as use of supercritical CO₂ conditions, modifiable content of metallic species, and presence of addnl. co-solvents, surface acidity inhibitors and H₂O₂ stabilizers. Reusability and stability of the bi-functional catalyst was showed through consecutive catalytic cycles.

Timofeeva, M. N. published the artcileEffect of the acid-base properties of Zr,Al-pillared clays on the catalytic performances in the reaction of propylene oxide with methanol, Synthetic Route of 1589-47-5, the publication is Applied Catalysis, B: Environmental (2011), 104(1-2), 54-63, database is CAplus.

A series of Zr,Al-pillared interlayered clays (Zr,Al-PILCs) have been prepared and characterized by X-ray diffraction, elemental anal., FT-IR and N2-adsorption/desorption analyses, 27Al NMR(MAS), FT-IR spectroscopy using pyridine, PhCN and CDCl3 as probe mols. It was found that textural and physicochem. properties of Zr,Al-PILCs depend on Zr content in clay. The relationship between the acid-base properties and catalytic performances of Zr,Al-PILCs was revealed in the synthesis of propylene glycol Me ether from methanol and propylene oxide. The results show that the conversion of propylene oxide and the selectivity to 1-methoxy-2-propanol decrease with increasing the amount of zirconium in Zr,Al-PILCs due to the change in acid-base properties.

Al-pillared interlayered clays (Al-PILCs) were synthesized by the exchange reaction between Na-clay and Al-hydroxypolycation solutions aged for 0.5-14 days and characterized by DRS-UV-vis, x-ray diffraction, FT-IR and N₂-adsorption/desorption analyses, Hammett acidity titration with n-butylamine and FT-IR spectroscopy using PhCN and CDCl₃ as probe mols. The aging time of Al-hydroxypolycation pillaring solution affects both the textural characteristics and the physicochem. properties of Al-PILCs. Al-PILCs were tested as catalysts for synthesis of propylene glycol Me ether from methanol and propylene oxide. Increase in Al content due to the prolonged aging time favors the increase in the activity of Al-PILCs.
