“…18,31,[41][42][43] An interaction between the electric field gradient of the framework surface and the CO 2 permanent quadruple moment could be induced by specific functionalities, but could also be facilitated upon an external stimulus such as pressure. 36 Therefore, the simultaneous increase in static pressure and the amount of guest in the pores are both factors probably influencing the adsorption process. For CPL-2, the carboxyl groups located near the Cu 2+ nodes should offer stronger sites for interaction with CO 2 as compared to the bpy pillars environment.…”

“…18 The adsorption of gases such as N 2 , O 2 , CO 2 and Xe on CPL-2 at relative low partial pressures at cryogenic temperatures also leads to distortion of the framework upon uptake of the gas that can be explained by a change in the coordination mode of Cu from pyramidal to square planar. 36 The magnitude of the hysteresis depended on the highest CO 2 pressures during loading, and was completely absent within the atmospheric pressure range. [33][34][35] Further experimental and computational studies have elucidated the capacity of these materials for CO 2 storage and delivery at medium pressures (up to 6 atm) and also showed that the observed hysteretic adsorption property is a function of the ultimate gas pressure.…”

The present study focuses on the long-range structural changes that occur in the porous coordination polymer Cu2(pzdc)2(bpy) (pzdc = pyrazine-2,3-dicarboxylate, bpy = 4,4'-bipyridine), also known as CPL-2, upon adsorption of CO2 at 25 °C and up to 7 atm. The structural data were gathered using in situ diffraction studies. CPL-2 exhibited an unexpected hysteretic adsorption-desorption process. The onset of hysteresis occurs at a pressure where full occupancy of the volume of the CPL-2 galleries is achieved while the framework retains a structure similar to what is observed under ambient conditions. Moreover, the onset occurs at a CO2 partial pressure larger than 2 atm and could be related to a combination of adsorbate-adsorbent interactions and forces exerted onto the CPL-2 framework. Pore volumes estimated from fits of the Dubinin-Astakhov isotherm model against the CO2 desorption data gathered at 25 and -78.5 °C, respectively, provided further evidence of the aforementioned CPL-2 framework changes. These findings are of relevance to the understanding of adsorption processes in metal organic frameworks or coordination polymers under conditions that are of relevance to gas capture at industrial scale.

“…Porous coordination polymers (PCPs), are novel materials constructed by coordinate bonds between multi-dentate ligands and metal atoms became new attractive porous materials as highly selective gas adsorption capability. [1][2][3][4][5][6] Some of results have indicated that porous coordination polymers (PCPs) might become promising adsorbents for CO 2 separation. [7][8][9][10][11][12] Considerable effort has been reported on the synthesis of PCP materials in the last several years.…”

Porous coordination polymers (PCPs) of Zn 2+ , oxalic acid and mixture ratio of 3-amino, 1,2,4triazole (Ataz) and 1,2,4-triazole (Taz) were synthesized to capture of carbon dioxide. A series of molar fraction Taz/(Taz + ATaz) prepared as 0.1;0.3;0.4;0.5;0.6;0.7 and 0.9 and also only ATaz and Taz ligand as 0 and 1 molar fraction respectively. Mixture of Taz and ATaz crystal induce new structure of 0.4, 0.5 and 0.6 molar fraction. Nitrogen adsorption of 50% mixture each ligand contribute the highest surface area as function of optimum condition to integrate pore space and amine group presence with adsorbed as 290 mgg -1 . This phenomena also shown through CO 2 adsorption amount as 135 mgg -1 , instead of 0.4, 0.6 and 0.7 molar fraction observed higher amount of CO 2 compared with only Taz ligand (X=1), indicate the integrated effects both of the ligand could generated the capture of higher amount of carbon dioxide.

Sintesis [Zn2(Oxac)(H2O) 2.5, atau ZOATW2.5, dibuat dari larutan metanol dan air dari Zn5(CO3)2(OH)6 dan dua jenis ligan yaitu 3-amino , 1,2,4-triazol (ATaz) dan asam oksalat (Oxac) pada 453 K selama 12 jam. Zn-oxac-ATaz yang dibuat dalam medan magnet 2T dan 4T menghasilkan struktur kristal baru yang terbentuk sebagai kristal triklinik, sedangkan kristal 0T dan 6T terbentuk sebagai Kristal ortorombik. Morfologi juga berubah menjadi empat persegi panjang dan memanjang dari kristal 4T, bentuk tak beraturan pada kristal 6T namun terbentuk lebih besar jika dibandingkan dengan kristal 0T. Meskipun tidak ada N2 yang teradsorbsi untuk semua kristal karena keberadaan gugus amina dapat menghalangi di dalam pori-pori, namun molekul CO2 dapat teradsorpsi karena interaksi kuat antara molekul NH2 dan CO2. Zn-oxac-Ataz 4T mengadsorbsi molekul CO2 yang signifikan sekitar 110 mg/g yang mengindikasikan kristal 4T disamping membentuk ruang pori yang lebih besar juga menunjukkan interaksi yang kuat antara molekul NH2 dan CO2.Kata kunci: polimer koordinasi berpori, isoterm adsorpsi, medan magnet, morfologi 1,2, As-synthesized [Zn2(Oxac)(ATaz)2].(H2O)2.5, referred to ZOATW2.5, was prepared from aqueous methanol solutions of Zn5(CO3)2(OH)6 and two kinds of ligands of
