Among them ZIF-8@3wt% g-C3N4 shows the highest adsorption capacity of 315 mg g−1 at 45 °C and 0–15 bar pressure. The rising adsorption trend of all prepared materials shows that these samples do not reach their saturation point and can still adsorb more CO2 even at a ...
Microporous materials exhibit fast CO2 adsorption rate with possible sacrificed capacity, while CO2 chemisorption on metal oxides is remarkable but kinetics and reactive area are critical. In order to adopt the advantages of both microporous sorbent zeolitic imidazolate frameworks (ZIF) and metal oxide ...
The amount adsorbed of CO_2 on the modified ZIF-8 sample by ammonia impregnation is the highest, having an increase.Zhang, Z.Xian, S.Xi, H.Wang, H.Li, Z.Chemical Engineering ScienceZhang Z J, Li Z. Improvement of CO2 adsorption on ZIF-8 crystals modified by enhancing basicity of ...

A post-combustion CO2capture adsorbent is made using ZIF8 as the sole precursor.TGA studies reveal high gravimetric adsorption capacity (10wt% at 30°C, 1bar)BET studies reveal high volumetric adsorption capacity (3.13mmol/g at 30°C, 1bar).Adsorption isotherms fit best to the Redlich-Peterso...
TG analysis showed that ZIF-8 had excellent thermal stability. ② Based on the synthesis of ZIF-8, a new magnetic adsorption material Fe O @ZIF-8 was successfully prepared by adding magnetic nanoparticles Fe O . XRD 3 4 3 4 and FTIR analysis showed that Fe O had been successfully ...
The CO2adsorption curves showed that theCO2adsorption properties of ZIF-8/PAN composite fiber membranes are in perfect accordance with their specific surface area trend, which means composite fiber membranes have higher CO2adsorption capacities with the increase of ZIF-8 contents. It indicates that if...
The ED-ZIF-8 selectivity for CO2/N2 adsorption gets signi?cantly improved, and is up to 23 and 13.9 separately at 0.1 and 0.5 bar, being almost twice of those of the ZIF-8. The isosteric heat of CO2 adsorption (Qst) on the ED-ZIF-8 becomes higher, while Qst of N2 gets slightly ...
It is likely that solids having Lewis acid sites on their surface and exhibiting high CO2 adsorption capacity will have enhanced activity for this cycloaddition reaction. The ZIF-8 framework, displaying large pores of diameter 11.6 Å, accessible through apertures of 3.4 Å [23], [24], [25...
