A series of carboxyl-group-functionalized imidazolium-based ionic liquids (CILs) were synthesized and grafted onto silica gel. The catalytic activity the resulting heterogeneous catalysts toward synthesis cyclic carbonateviacycloaddition reactions epoxide CO2 was studied. effect on reaction ILs' structures conditions such as temperature, time, pressure, amount catalyst used, systematically investigated. For comparison, silica-grafted ILs with without hydroxyl groups also used to catalyze...
Poly(ethylene oxide)-based solid-state electrolytes are widely considered promising candidates for the next generation of lithium and sodium metal batteries. However, several challenges, including low oxidation resistance cation transference number, hinder poly(ethylene broad applications. To circumvent these issues, here, we propose design, synthesis application a fluoropolymer, i.e., poly(2,2,2-trifluoroethyl methacrylate). This polymer, when introduced into solid electrolyte, improves...
Aluminum salen complexes bearing appended quaternary ammonium salt substituents have been synthesized and shown to be effective catalysts for the coupling of epoxides carbon dioxide generate cyclic carbonates. 27Al NMR spectra demonstrated that these exist as both five- six-coordinate Al(III) species in dimethylsulfoxide (DMSO) solution, whereas only a five-coordinate was detected (salen)AlCl analogue presence an external onium salt. The group tethered on ligand found play important role...
So far, ligand steric effects of the α-diimine nickel catalysts on polyolefin branching densities are not systematically investigated. Generally, in contrast to palladium systems, polyethylene obtained by increased when more sterically encumbering substituent was employed. In this contribution, we described synthesis and characterization a series ligands corresponding bearing diarylmethyl moiety varied ligands. ethylene polymerization, catalytic activities [(2.82–15.68) × 106 g/(mol Ni·h)],...
Glutathione (GSH) as a biothiol is an essential peptide related to various diseases. Although multiple strategies for biothiols detection have been developed, there increasing demand sensors that can differentiate GSH from cysteine (Cys) and homocysteine (Hcy), owing the similar structures thiol groups in these amino acids. Herein, we report novel Eu3+/LAPONITE (Lap)-based organic/inorganic hybrid material selective of via “off–on” process. The fluorescence Eu(DPA)3@Lap-Tris be quenched by...
A facile strategy has been demonstrated for the selective synthesis of highly stereoregular polyesters with cis-2,3-(exo, exo) or trans-2,3-(exo, endo) repeating units by organocatalysts mediated alternating copolymerization cyclohexene oxide and norbornene anhydride (NA) stereoisomers. The geometrical structure polyester can be tuned simply modulating type NA isomers (endo- exo-NA), monomer feed ratio, reaction temperature. cis- (>99%) trans-polyesters exhibit high glass transition...
Novel bio-based non-isocyanate polyurethanes with tunable mechanical and self-healing properties are successfully synthesized.
Abstract All‐solid‐state polymer electrolytes (ASPEs) with excellent processivity are considered one of the most forward‐looking materials for large‐scale industrialization. However, contradiction between improving mechanical strength and accelerating ionic migration ASPEs has always been difficult to reconcile. Herein, a rational concept is raised high‐entropy microdomain interlocking (HEMI‐ASPEs), inspired by entropic elasticity well‐known in biochemical sciences, introducing newly...
In order to effectively convert greenhouse gas CO2 into high value-added chemicals, simple and sustainable methods are urgently needed. this study, a novel metal-anchored ionic porous organic polymer (M-iPOP) named Zn-HUT4 was synthesized via very low-cost synthesis process. Further investigation conducted the use of as heterogeneous catalyst in cycloaddition reaction with epoxides. The obtained had rich structure abundant metal anchor points, which can promote mass transfer offer...
Abstract. Since 2000, CO2 emissions from emerging economies have outstripped those of developed economies. To limit global warming to under 1.5 ∘C by 2100, over 100 proposed net-zero carbon targets. Yet the supportive data are lacking – no inventory emission outlines detailed sources sector or distribution at subnational level for these Here, we redress balance establishing a dataset an energy-related that covers 47 sectors and eight energy types in 40...

Mainland Southeast Asian (MSEA) countries (Cambodia, Laos, Thailand, Myanmar, and Vietnam) are likely to become one of the next hotspots for emission reduction, since CO2 emissions in this area will have a two-thirds increase by 2040 due rapid economy growth associated energy consumption. As most vulnerable areas climate change, MSEA need develop low-carbon roadmaps based on accurate data. This study provides inventories 2010-2019, IPCC territorial accounting approach , including from five...
Using greenhouse gas CO2 as the carbonyl source, preparation of methyl propionate (MP) via synergistic effect photo- and photothermal-catalysis instead traditional thermal catalysis ethylene hydroesterification was first proposed. Ru-loaded black TiO2 (B–TiO2/Ru) selected a photothermal-catalyst since Ru has been used an excellent catalyst for hydroesterification, with high photothermal can reduce to more active CO in reaction under light irradiation. The effects from B–TiO2/Ru improve yield...
