Abstract

The sorption properties of [Zr6O4(OH)4(NH3 +-BDC)6]Cl6·xH2O (MOR-1) and H16[Zr6O16(H2PATP)4]Cl8·xH2O (MOR-2) towards ReO4 and TcO4 were studied in detail. Both MOR-1 and MOR-2 are very effective sorbents for ReO4 and TcO4 anions, with MOR-2 showing the highest sorption capacity (up to 4.1 ± 0.4 mmol g−1) among the known metal organic materials. Importantly, the exceptional sorption capacity of MOR-2 is retained even under conditions simulating acidic nuclear waste. In addition, MOR-1 and MOR-2 exhibit selective luminescence ReO4 sensing properties, demonstrated for the first time for MOF materials.
