【Journal of Materials Science】Nitrogen-doped graphene-supported molybdenum dioxide electrocatalysts for oxygen reduction reaction
A simple one-step pyrolysis strategy has been developed to prepare molybdenum dioxide supported on nitrogen-doped graphene (MoO2/NG) as electrocatalyst for oxygen reduction reactions (ORR). Homogeneous anchoring of MoO2 nanoparticles on nitrogen-doped graphene was achieved for the composite synthesized at 500 °C (MoO2/NG-500). For the first time, the MoO2/NG composite manifests considerable ele...

Enhanced carbon dioxide capture in an indolebased microporous organic polymer via synergistic effects of indoles and their adjacent carbonyl groups
A carbonyl-functionalized indole-based microporous organic polymer (PKIN) was designed and synthesized in the presence of the FeCl3 catalyst by a facile direct oxidative coupling reaction. Taking advantage of the synergistic effect of indoles and their adjacent carbonyl moieties on carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches up to 6.12 mmol g-1 (1.0 bar, 273 K)...

Post-combustion carbon dioxide capture via 6FDA/BPDA-DAM hollow fiber membranes at sub-ambient temperatures
Post-combustion carbon dioxide capture has the greatest near-term potential compared to other technological pathways to mitigate CO2 emissions. The hybrid membrane and cryogenic distillation process developed at American AirLiquide allows sub-ambient temperature (?50 °C to ?20 °C) CO2 capture to be cost effective. In previous work, Matrimid® hollow fiber membranes with so-called “nodular” ...

Alternating Copolymerization of Cyclohexene Oxide and Carbon Dioxide Catalyzed by Noncyclopentadienyl Rare-Earth Metal Bis(alkyl) Complexes
The
syntheses of several dialkyl complexes based on rare-earth metal were
described. Three beta-diimine compounds with varying N-aryl substituents (HL1 =
(2-CH3O(C6H4))N=C(CH3)CH=C(CH3)NH(2-CH3O(C6H4)), HL2 = (2,4,6-(CH3)(3)
(C6H2))N=C(CH3)CH=C(CH3)NH(2,4,6-(CH3)(3)(C6H2)), HL3 = PhN=C(CH3)CH(CH3) NHPh)
were treated with Ln(CH2SiMe3)(3)(THF)(2) to give dialkyl complexes L(1)Ln
(CH2SiMe...

45. From a flexible hyperbranched polyimide to a microporous polyimide network: Microporous architecture and carbon dioxide adsorption
A dianhydride monomer 2, 5-bis(3, 4-dicarboxyphenoxy)-4′-phenylethynyl biphenyl (PEPHQDA) containing a chain extendable phenylethynyl pendant group has been successfully synthesized via successive nucleophilic substitution, Sonogashira cross-coupling, hydrolysis and dehydration reactions. A flexible microporous polyimide network has been prepared based on the use of triamine (TAPOB), affording hy...

41. Microporous polyimide networks constructed through a two-step polymerization approach, and their carbon dioxide adsorption performance
Based on a dianhydride monomer 2,5- bis(3,4- dicarboxyphenoxy)-4''''''''''''''''-phenylethynyl biphenyl (PEPHQDA) containing a crosslinkable phenylethynyl pendant group, microporous polyimide networks (HBPI-CRs) were prepared through a two- step pathway combining polymerization and crosslinking reactions. Specifically microporous features such as surface morphology, microporous structure and unifo...

[Sensors Actuators: B. Chem.] A water-soluble near-infrared (NIR) fluorescence activation probe for efficient detection of dissolved carbon dioxide
.A near-infrared (NIR)
fluorescent “turn-on” probe is presented for dissolved carbon dioxide (dCO2)
detection in aqueous medium. This
probe is based on perylene
bisimide-functionalized hyperbranched polyethylenimine (PBI-HPEI) polymer,
which exhibits typical NIR fluorescence
due to the excimer emission of π-π
stacked PBI fluorophores.
Both UV-Vis absorption and fluorescent spectroscopy studies...
