Recent Question/Assignment

The report must be 20-25 pages (Figures, tables, table of contents, reference list, summary/abstract do not count in this number of pages). Additional information (spectra or other raw data, etc.) can be included as appendix outside this framework.
If the source is a book it must have a page number of the text. (A quotation must be enclosed in quotation marks (-...-) and after the quotation there must be a reference to the source and page number (use EndNote).
PROSJEKT : Metal-organic frameworks as energy carriers and adsorbents in energy-efficient separation processes. compression between these two mofs
UIO-66-NH2 and UIO66-(NH2)2
How do the properties of UiO-66-NH2 and UiO-66-(NH2)2, specifically their ability to act as energy carriers and adsorbents, differ, and how might these differences impact their performance in energy-efficient separation processes?
I hva done a lab experiment. I synthesized 2,5-diaminoterephthlic acid (linker) via a three-step process (confirmed by NMR). then synthesized UiO-66-NH2 and UiO-66-(NH2)2 MOFs. Characterization included N2 adsorption/desorption (BET), FTIR (functional groups), and XRD (structural similarity). Her is my experiment
I need from you to write a complete report.
Comments from supervisor
MOFs are crystalline compounds with precisely defined pores, which means their sorption properties will be very well defined and homogenous. Due to their variability in chemical functionalization, they are heavily investigated materials in adsorption of gases, like hydrogen, methane, carbon dioxide, and separation processes, e.g. hydrogen purification, CO2 capture, ethylene/ethane and propylene/propane separation. Some of these processes are important for the development of hydrogen technology in the energy transition; others are important industrial separation processes, where the development of new materials that make the process more energy efficient will lead to substantial energy savings Metal-organic frameworks (MOFs) are crystalline coordination networks that are formed by self-assembly of inorganic and organic building units. These frameworks can have large pores in the order of 0.3-3 nm diameter. Because many different inorganic and organic building units can be used in MOF synthesis, they have quite versatile properties with potential use in a wide range of applications. Therefore, MOFs are an exciting class of nanostructured materials and a large amount of research is performed currently in quite a lot of different application areas. The most prominently investigated property of MOFs is their function as adsorbent for the capture and/or separation of industrially relevant fluids (gases or liquids), e.g. in CO2 capture, hydrogen purification, or hydrocarbon separation. They are also fascinating materials to investigate for use in photovoltaic devices, fuel cells and batteries, as sensors and in (electro-)catalysis, for instance in water splitting (hydrogen production) or carbon dioxide reduction. Activities in the research group focuses on materials discovery (the synthesis of new compounds), the characterization of these compounds (e.g. investigation of their crystal structure and properties like thermal stability) and the investigation of application oriented properties. this project focus on synthesis and characterization of compounds using appropriate techniques and including sorption measurements of N2. I attempt to include both synthesis and characterization in the project.
• You find my lecture notes on gas adsorption on this links. Theres also a copy of an Oxford Chemistry Primer on Surfaces, where the first 13-17 pages are of immediate relevance

• i have found this article (pp. 19-22) to be relevant to my topic
• I have found this article and maybe it is relevant but not qiute directly. You can look at it as reference and what we need to include in the report. materials-11-00589.pdf
