Capture and immobilization of gaseous ruthenium tetroxide RuO₄ in the UiO-66-NH₂ metal–organic framework

Abstract

106Ru is a radioactive isotope usually generated by the nuclear industry within power plant reactor. During a nuclear accident, 106Ru reacts with oxygen, leading to the production of highly volatile...

Identifying pathways to metal–organic framework collapse during solvent activation with molecular simulations

“…[6][7][8][9][10] MOFs are the subject of intense research due to their record-breaking levels of porosity, [11][12][13][14][15] modular construction enabling ne-tuning of metal [16][17][18] and linker [19][20][21][22] chemistry, and the resultant diversity in terms of materials properties. 2,[23][24][25][26][27] Accordingly, there have been many studies focusing on the applicability of MOFs to industrially important small molecule separation 1,28-30 and storage [31][32][33][34] applications.…”

Test Bench Development and Application to a Parametric Experimental Study on the Dynamic Adsorption Capacity of Noble Gases (Kr, Xe) in the Metal–Organic Framework HKUST-1

“…To contribute to this latter point, the present work deals with the development of an experimental test bench allowing the dynamic study of noble gas adsorption (Xe, Kr) by MOFs under nuclear accident conditions listed above. A homemade device named SAFARI (implemented at IRSN-Cadarache-France), initially used for volatile iodine and RuO 4 ( g ) capture, , has been adapted for the study of noble gases capture, notably with the development of an online analysis method for krypton and xenon gases by gas chromatography coupled with a mass spectrometer. In this work, the reference copper trimesate-based material HKUST-1 was considered and synthesized.…”
