CO2 Adsorption by Functionalized Nanoporous Materials: A Review

Gargiulo, Nicola, Pepe, Francesco, Caputo, Domenico·2014·Journal of Nanoscience and Nanotechnology

Abstract

This review highlights the recent advances in the development of functionalized nanoporous adsorbents for CO2 capture. Three main classes of materials are taken into account: zeolites, mesoporous silicates, and metal organic frameworks (MOFs). Proper modification of the cation content of zeolites, as well as the introduction of functional groups such as amine groups into ordered mesoporous silicates and MOFs, greatly enhance the CO2 adsorptive properties of these substrates. Specifically, cation-exchanged zeolites can be currently considered the benchmark for ordered nanoporous CO2 adsorbents, finding application also on a plant scale. Amino-functionalized mesoporous silicates tend to show a high affinity toward CO2: while this could be an advantage when pushed purification is needed, it also implies that full regeneration of the adsorbent can be achieved only by putting its surface in contact with a completely CO2-free environment. On the contrary, similarly modified MOFs show higher CO2 adsorption working capacities: this potentially makes them even better candidates than their mesoporous inorganic homologues for a plant scale use. However, the persisting lack of reliable methods for the pelletization of both ordered mesoporous silicates and MOFs creates a care for further development efforts in the next future.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
