Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1354948

When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading to the formation of Si-islands/aggregates with a concomitant loss of Brønsted...

Loading metal-organic frameworks with aluminium

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1234705

We here demonstrate impregnation of metallic Al in MOFs; the highest loading was seen for UiO-67. The samples were analysed by TGA, ICP, DSC, BET and solid state NMR. ICP shows that the samples contain Al. 27Al NMR of Al@UiO-67 confirms that Al is present in metallic form. Surface area and pore volu...

Nanoporous Intergrowths: How Crystal Growth Dictates Phase Composition and Hierarchical Structure in the CHA/AEI System

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1260838

Some of the most important nanoporous materials that are used for industrial applications are formed as intergrowths between structurally related phases. Further, the specific properties and functions are often strongly related to the nature of these intergrowths. By their nature such structures are...

In-Situ Atomic Force Microscopy Study of the Dissolution of Nanoporous SAPO-34 and SAPO-18

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1312554

In-situ atomic force microscopy has been used to investigate the dissolution behavior of industrially relevant silicoaluminophosphate catalysts SAPO-34 and SAPO-18. Spiral growth is prevalent on these materials and it is common for the spirals to be composites of multiple dislocation sources. The sp...

High-Pressure Adsorption of CO2 and CH4 in Zr-MOFs

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1163011

Adsorption equilibrium of CO2 and CH4 at three different temperatures was measured on three isoreticular Zr-MOFs: Zr(1,4-BDC) (UiO-66), Zr(4,4′-BPDC) UiO-67, and Zr(2,6-NDC) (DUT-52). Adsorption equilibrium data was measured at 298, 313, and 343 K up to 30 bar for CO2 and 80 bar for CH4. The three a...

On the development of Vacuum Swing adsorption (VSA) technology for post-combustion CO2 capture

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1051567

A metal-organic framework, UiO-66, has been evaluated as adsorbent in a post-combustion vacuum swing adsorption (VSA) process. Equilibrium isotherms of the most relevant gases (CO2 and N2) as well as breakthrough curves measured using synthetic flue gas containing 15 mol% CO2 without and with 9 mol%...
