Extremely enhanced CO2 uptake by HKUST-1 metal–organic framework via a simple chemical treatment

Mapping the Cu-BTC metal–organic framework (HKUST-1) stability envelope in the presence of water vapour for CO2 adsorption from flue gases

“…copper benzene-1,3,5-tricarboxylate or HKUST-1 [11], is one of the most extensively studied MOFs for gas separation [12][13][14][15] and storage [16,17] due to its high surface area (normally in a range of 600-1600 m 2 g À1 for samples synthesised in a laboratory), large pore volume (ca. 0.70 cm 3 g À1 ) [18] and good thermal stability (thermally stable up to 350°C) [19].…”

“…To date, the primary research interest of CO 2 adsorption on HKUST-1 has been focused on the manipulation of the CO 2 adsorption capacity/selectivity by using materials design strategies [17,26] or postsynthetic modification approaches [15]. However, apart from tuning the CO 2 /N 2 selectivity to increase the CO 2 capture efficiency, the effect of the presence of water vapour in flue gas streams also needs to be considered to properly assess their performance as potential CO 2 capture materials.…”

Behavior of a Metal Organic Framework Thin‐Film at Elevated Temperature and Pressure as Studied with an Autoclave‐Inserted Atomic Force Microscope

“…Within this context, HKUST‐1, consisting of copper (II) ions and 1,3,5‐BenzeneTriCarboxylate (BTC, and also known as trimesic acid) linkers, is one of the most studied (SUR)MOFs ,. In both bulk and as a membrane several functionalities of HKUST‐1, such as its gas sorption properties of N 2 , H 2 and CO 2 have been studied extensively and have shown excellent prospects . Importantly, a lot of research has been performed on optimizing the synthesis of HKUST‐1 SURMOFs.…”

“…[36,37] In both bulk and as a membrane several functionalities of HKUST-1, such as its gas sorption properties of N 2 , H 2 and CO 2 have been studied extensively and have shown excellent prospects. [38][39][40][41][42][43] Importantly, a lot of research has been performed on optimizing the synthesis of HKUST-1 SURMOFs. An easy, albeit somewhat elaborate, synthesis procedure has been developed by Shekhah et al to produce SURMOF thin-films in a highly controlled fashion by separating the growing stages of the metal ions and the organic linkers, known as the Layer-by-Layer (LbL) method ( Figure 1b).…”

Pseudopeptide bioconjugate additives for CO2 separation membranes

“…Inorganic or hybrid additives (i.e. zeolites, carbon molecular sieves, metal organic frameworks or zeolitic imidazolate frameworks) have been mainly used to provide additional free fraction volume (FFV) and/or ‘sieving’ effects for increasing permeability and/or selectivity. For the CO 2 separations of interest in this work, poly(ethylene oxide) (PEO) based oligomer additives have also been reported for increasing chain mobility and decreasing PEO crystallinity …”
