Reactive Adsorption of Ammonia on Cu-Based MOF/Graphene Composites
Abstract
New composites based on HKUST-1 and graphene layers are tested for ammonia adsorption at room temperature in both dry and moist conditions. The materials are characterized by X-ray diffraction, FT-IR spectroscopy, adsorption of nitrogen, and thermal analyses. Unlike other MOF/GO composites reported in previous studies, these materials are water-stable. Ammonia adsorption capacities on the composites are higher than the ones calculated for the physical mixture of components, suggesting the presence of a synergetic effect between the MOF and graphene layers. The increased porosity and dispersive forces being the consequence of the presence of graphene layers are responsible for the enhanced adsorption. In addition to its retention via physical forces, ammonia is also adsorbed via binding to the copper sites in HKUST-1 and then, progressively, via reaction with the MOF component. This reactive adsorption is visible through two successive changes of the adsorbents' color during the breakthrough tests. More ammonia is adsorbed in moist conditions than in dry conditions owing to its dissolution in a water film present in the pore system.

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.
