“…Therefore, their functionalized counterparts have attracted considerable attention because they are more effective compared with the original ones, such as their higher separation efficiency, 7 gas storage, 8 catalytic performance 9 and luminescence capability. 10 H 2 and CH 4 are considered as environmentally friendly energy carriers and have received much attention. Nevertheless, the presence of CO 2 in them remarkably decreases their heat values.…”

Design of amine-functionalized metal–organic frameworks for CO₂ separation: the more amine, the better?

A total of 41 825 metal-organic frameworks (MOFs) were computationally screened toward the design of amine-functionalized MOFs for CO 2 separation. Both the optimal species and number of amine functional groups were examined for eight MOFs with good performance in terms of CO 2 uptake and selectivity. It was revealed that more amine functional groups grafted on the MOFs do not lead to a better CO 2 separation capability, and the concept of saturation degree of functional groups was proposed. The ethylenediamine-functionalized MOF-74 membrane was predicted to possess high CO 2 permeation separation capability, which was confirmed by the parallel experimental test of gas permeation.Metal-organic frameworks (MOFs) have received tremendous interest in the past few decades due to their large potential for H 2 storage, 1 CO 2 capture, 2 catalysis, 3 gas separation and purification, 4 liquid separation 5 and drug delivery. 6 However, the performance of many synthesized MOFs cannot satisfy industrial demands. Therefore, their functionalized counterparts have attracted considerable attention because they are more effective compared with the original ones, such as their higher separation efficiency, 7 gas storage, 8 catalytic performance 9 and luminescence capability. 10 H 2 and CH 4 are considered as environmentally friendly energy carriers and have received much attention. Nevertheless, the presence of CO 2 in them remarkably decreases their heat values. Moreover, in a moist environment, CO 2 can react with water to produce carbonic acid, leading to corrosive effects not only on the equipment but also on the pipes during transportation. 11 Consequently, CO 2 separation from H 2 or CH 4 is crucial in the processing of clean fuels. Toward this end, the functionalization of MOFs by amine functional groups has been recognized as an effective technique to improve the adsorption and separation of acidic CO 2 . 12 In the literature, a larger number of amine-functionalized MOFs have been synthesized and tested. 13 Vaidhyanathan et al. 14 reported the crystallographic resolution of amine-functionalized MOFs and their analysis showed that the low-pressure binding and large uptake of CO 2 were influenced by three factors, i.e., strongly interacting amine functional groups, suitable pore size and the cooperative binding of CO 2 molecules. Ahnfeldt et al. 15 synthesized four amine-functionalized MOFs including CAU-1-NH 2 , CAU-1-NHCH 3 , CAU-1-NH 2 (OH) and CAU-1-NHCOCH 3 , and examined the effects of time and temperature.While a wide variety of MOFs can be modified for CO 2 separation, it remains elusive which specific MOFs are suitable to be functionalized, which functional groups have the best improvement and what is the optimal number of functional groups. In most experimental efforts, many MOFs were modified by trial-and-error, resulting in a slight chance of successful synthesis and actual enhancement in performance. It is thus of great significance to unravel how functionalized MOFs can be rationally designed from a computa...

“…[11a] The silver exchanged form of RPM-3 has also been shown to exhibit higher ethylene detection ability by a p complexation pathway, as monitored by fluorescence and Raman spectroscopic methods. [34] Porous MOF-based adsorbents for selective separation of small hydrocarbon molecules have received significant interest from researchers because of their exceptional separation selectivity, permanent and sustainable microporosity, and the ease of pore tunability. Moreover, a vast number of porous MOFs with a wide range of surface area and pore characteristics (e.g., volume, width, type of surface functionalization) are already available, so that researchers can easily select plausible adsorbent materials for particular applications.…”

The effective separation of small hydrocarbon molecules (C 1 -C 4 ) is an important process for the petroleum industry, determining the end price of many essential commodities in our daily lives. Current technologies for separation of these molecules rely on energy-intensive fractional distillation processes at cryogenic temperature, which is particularly difficult because of their similar volatility. In retrospect, adsorptive separation using solid-state adsorbents might be a cost-effective alternative. Several types of solid-state adsorbents (e.g., zeolite molecular sieves) were tested for separation of small hydrocarbon molecules as a function of pressure, temperature, or vacuum. Among different types of plausible adsorbents, metal organic frameworks (MOFs), a class of porous, crystalline, inorganicorganic hybrid materials, is particularly promising. In this brief comment article, we discuss the separation properties of different types of solid-state adsorbents, with a particular emphasis on MOF-based adsorbents for separation of C 2 hydrocarbon molecules.

“…Hence, there is a need for simple, compact, inexpensive, portable, and reliable ethylene sensors that could be used parallel in controlling ethylene concentration systems. The technologies that have been commonly used include gas chromatography [3], optical sensors [4], colorimetric sensors [5], amperometric sensors [6], photoluminescence sensors [7], gravimetric sensors [8], and chemoresistive and capacitive sensors [9,10]. From technologies has been mentioned, chemoresistive can meet criteria desired One of material frequently used as sensitive layer in gas sensor is tin oxide (SnO2), because of its properties including fast-response speed, high chemical stability, and prominent selectivity.…”

Abstract. Ethylene gas is a gas naturally released by fruits. The maturity level of these fruits could be predicted from the amount of ethylene around them. To maintain the freshness of these fruits, the concentrations of surrounding ethylene need to be monitored. Therefore, suitable gas sensor ethylene were still in progress to get good respond. In this paper systhesis of pure SnO2 nanoparticle from SnCl2.2H2O and water solution in precipitation method was held. The tin oxide powder was obtained in good distribution with nanoparticle size. This nanoparticle powder was formed into thick film, using ethylene glycol as solvant. To observe this sensor characteristics, several test was held in various conditions. Gas testing used pure ethylene gas show better respond at higher than room temperature but recovery time still unsatisfying.
