Title (EN) OVERCOMING TWO CARBON DIOXIDE ADSORPTION STEPS IN DIAMINE-APPENDED METAL-ORGANIC FRAMEWORKS
(FR) FRANCHIR DEUX ÉTAPES D'ADSORPTION DE GAZ CARBONIQUE DANS DES STRUCTURES ORGANOMÉTALLIQUES DE DIAMINE AJOUTÉE
Abstract:
(EN) Primary, secondary (1°,2°) alkylethylenediamine- and alkylpropylenediamine- appended variants of metal-organic framework are provided for CO2 capture applications. Increasing the size of the alkyl group on the secondary amine enhances the stability to diamine volatilization from the metal sites. Two-step adsorption/desorption profiles are overcome by minimizing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg2(dotpdc) (dotpdc4- =4,4"-dioxido-[1,1':4',l"-terphenyl]-3,3"-dicarboxylate), yields diamine-appended adsorbents displaying a single CO2 adsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg2(pc-dobpdc) (pc-dobpdc4- = 3,3-dioxidobiphenyl-4,4-dicarboxylate, pc = para-carboxylate) also leads to a single CO2 adsorption step with bulky diamines. By relieving steric interactions between adjacent ammonium carbamate chains, these frameworks enable step-shaped CO2 adsorption, decreased water co-adsorption, and increased stability to diamine loss. Variants of Mg2(dotpdc) and Mg2(pc-dobpdc) functionalized with large diamines such as N-(n-heptyl)ethylenediamine have utility as adsorbents for carbon capture applications.
(FR) Des structures organométalliques de variantes primaire, secondaire (1°, 2°) alkyléthylènediamine et alkylpropylènediamine ajoutées sont prévues pour des applications de capture de CO2. La taille accrue du groupe alkyle sur l'amine secondaire améliore la stabilité à la volatilisation de diamine à partir de sites métalliques. Des profils d'adsorption/désorption en deux étapes sont franchis en minimisant les interactions stériques entre des chaînes de carbamate d'ammonium adjacentes. Par exemple, le squelette expansé isoréticulé Mg2(dotpdc) (dotpdc4- =4,4"-dioxido-[1,1':4',l"-terphenyl]-3,3"-dicarboxylate), ce qui permet d'obtenir des adsorbants à diamine ajoutée en une seule étape d'adsorption de CO2. De plus, l'utilisation du cadre isomérique Mg-IRMOF-74-II ou Mg2(pc-dobpdc) (pc-dobpdc4- = 3,3-dioxidoiphényle-4,4-dicarboxylate, pc = para-carboxylate) conduit également à une seule étape d'adsorption de CO2 avec des diamines volumineuses. En libérant des interactions stériques entre des chaînes de carbamate d'ammonium adjacentes, ces structures permettent une adsorption de CO2 par étape, une coadsorption d'eau réduite et une stabilité accrue face à la perte de diamine. Des variantes de Mg 2 (dotpdc) et de Mg 2 (pc-dobpdc) fonctionnalisées avec de grandes diamines telles que la N-(n-heptyl)éthylènediamine ont une utilité en tant qu'adsorbants pour des applications de capture de carbone.
