A novel zirconium phosphonate adsorbent for highly efficient radioactive cesium removal
, 2021A novel layered functionalized zirconium phosphonate adsorbent (DB-ZrP) was prepared by intercalating of 3, 4-dibenzo-21-crown-7 into the interlamination of α-ZrP.

Materials Chemistry and Physics, 1993
Abstract The preparation and characterization of a number of layered zirconium compounds containing inorganic phosphorus groups as well as organic phosphonate groups are described. Thermal decomposition of ZrF62− in the presence of mixed phosphoric and phenylphosphonic acids leads to formation of a staged compound in which the organic and inorganic ...

Hybrid Membranes Based on Zirconium Phosphonates
Membranes and Membrane Technologies, 2020Phosphonates with the composition Zr(PO3(CH2)nPh)2 with n = 0, 1, and 3 are synthesized. Hybrid membranes based on an MF-4SK membrane and the synthesized phosphonates are made. The influence of the dopant, its concentration, and synthesis method on the ion-conducting properties of the membranes is studied in comparison with hybrid membranes based on α ...

Catalytic Activity of Myoglobin Immobilized on Zirconium Phosphonates
Langmuir, 2004The adsorption and catalytic activity of myoglobin (Mb) on zirconium phosphonates (a-zirconium benzenephosphonate (alpha-ZrBP), a-zirconium carboxyethanephosphonate (alpha-ZrCEP), and a novel layered zirconium fluoride aminooctyl-N,N-bis(methylphosphonate) (ZrC8)) were investigated.

Polymerization of aniline on copper zirconium phosphate and a mixed zirconium phosphonate
Polyhedron, 1994Abstract Oxidative polymerization of aniline was performed using both CuZr(PO 4 ) 2 (CuZrP) and Zr[O 3 P(CH 2 ) 3 COOH] 0.75 (O 3 POH) 1.25 [ZrP(bt) 0.75 (OH) 1.25 ] as catalysts. In the CuZrP reaction, the non-conducting emeraldine base form of polyaniline (PANI) formed on the surfaces of the phosphate microcrystals. When exposed to HCl, the solid

Organically pillared microporous zirconium phosphonates
Journal of the Chemical Society, Dalton Transactions, 2002There is great technological interest in the design of multifunctional microporous materials, particularly those with pores in the 10–20 A range. The many attempts to achieve this goal through cross-linking zirconium phosphate-like layers by use of several types of diphosphonic acids will be described. A variety of functionalized pillared materials are

Chapter 2. Zirconium Phosphonates
2011This contribution presents a survey of the various aspects of the chemistry of Zr phosphonates, throughout 30 years of activity of the Laboratory of Inorganic Chemistry of Perugia on this topic. These inorganic–organic compounds are characterized by a very low solubility and chemical robustness, and their structure and reactivity can be easily ...

Intercalates of zirconium phosphates and phosphonates
1991Abstract Tetravalent metals such as Zr, Ti, Sn, Ce, Th, etc. can be bound to oxygens belonging to XO4 and/or RXO3 groups (X = pentavalent element; R =inorganic or organic group such as -H, -OH, -CH3, -C6H5, etc.) and from such a combination many fibrous, layered, and three-dimensional structures can be obtained.

Bifunctional Mesoporous Zirconium Phosphonates for Delivery of Nucleic Acids
Inorganic Chemistry, 2013The bifunctional mesoporous zirconium phosphonates (ZrBFs) were synthesized through surfactant-assisted co-condensation of ZrCl(4) with two different phosphonic acids, both 1-phosphomethylproline (H(3)PMP) and 1,4-bis(phosphomethyl)piperazine (BPMP), in a one-pot procedure.
