Synthesis of NU-1000 Nanoparticles — Presentation Detail — Celebration of Scholars

Instructions

Student presentations must have a faculty sponsor.

Abstracts must include a title and a description of the research, scholarship, or creative work. The description should be 150-225 words in length and constructed in a format or style appropriate for the presenter’s discipline.

The following points should be addressed within the selected format or style for the abstract:

A clear statement of the problem or question you pursued, or the scholarly goal or creative theme achieved in your work.
A brief comment about the significance or uniqueness of the work.
A clear description of the methods used to achieve the purpose or goals for the work.
A statement of the conclusions, results, outcomes, or recommendations, or if the work is still in progress, the results you expect to report at the event.

Presenter photographs should be head and shoulder shots comparable to passport photos.

Abstract

Metal-organic frameworks (MOFs) are crystalline, porous materials synthesized from metallic clusters linked by organic ligands. MOFs can be used in diverse applications such as gas separation and storage, sensing, and catalysis. NU-1000, a Zr-based MOF with tetratopic linkers, is thermally and hydrolytically stable, and contains large mesoporous channels. The typical NU-1000 synthesis combines an initially homogeneous solution of zirconia nodes and benzoic acid in dimethylformamide with a solution of linker (4,4′,4″,4″′-(pyrene-1,3,6,8-tetrayl)tetrabenzoic acid; TBAPy) in dimethylformamide and aging at an elevated temperature. The typical product is composed of large hexagonal rods that are microns in length and contain substantial amounts of a denser phase similar to NU-901. Data will be presented showing that phase pure NU-1000 with particle size in the range of 45 nm to 30 microns can be reproducibly synthesized by controlling experimental conditions. Finally, when very low modulator concentrations were employed, NU-1000 sol-gels formed, which were converted into xerogels by high temperature treatment and aerogels by supercritical CO₂ extraction.
