Tetravalent Metal Phosphonate-Phosphate Hybrids as Catalyst Supports and Ion Exchange Materials [PDF]

open access: yes, 2020
This work centers on recycling of Rh catalysts and utilizing ion exchange to separate nuclear waste. In the area of Rh-type catalyst supports, non-porous zirconium phosphate nanoplatelets (ZrP) were utilized to provide sufficient outside surface area ...

Stable Ultramicroporous Metal–Organic Framework with Hydrophilic and Hydrophobic Domains for Selective Gas Adsorption

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 40, September 26, 2025.
The ultramicroporous pores of TUB41 selectively host water and CO2 molecules at distinct hydrophilic and hydrophobic compartments without competition. Abstract Herein, we report the thermal and chemical stability, and the gas adsorption behavior, of a mixed‐linker phosphonate MOF, [Cu(4,4′‐bpy)0.5(1,4‐NDPAH2)], namely TUB41 (where bpy = bipyridine and ...
