An overview on the developments of zirconium phosphate (ZrP) and its organic derivatives in heterogeneous catalysis in recent years is reported in the present review. Two basic aspects have been emphasized: first, the catalytic properties of zirconium phosphates were discussed, with particular attention to the effect of surface acidity and hydrophobic/hydrophilic character, textural properties, and particle morphology on the catalytic performances. Then, the use of zirconium phosphates as support for catalytic active species was reported, including organometallic complexes, metal ions, noble metal, and metal oxide nanoparticles. Zirconium phosphate plays, in those cases, a dual role, since it promotes the dispersion and stabilization of the catalysts, thanks to their interaction with the active sites on the surface of ZrP, and facilitates the recovery and reuse of the catalytic species due to their immobilization on the solid support.

The layer structured zirconium phosphate (ZrPO 3 ) can be intercalated with atoms, molecules, small organic groups and even polymers. The structures and properties of the ZrPO 3 intercalation compounds can be deliberately tuned, leading to promising potential applications in many fields. This article provides a brief review on the experimental results of the ZrPO 3 intercalation compounds, with the focus on the polymer/-ZrPO 3 nano-composites. The computer simulations of the ZrPO 3 intercalation compounds at the atomic level play a significant role in designing and understanding the properties of ZrPO 3 , and in the promotion of the applications of compounds. -Zirconium phosphate, intercalations, nano-composites Citation:Tang M, Yang T S, Zhang Y.

“…4,5 The H + of the P-OH moiety in ZP can be exchanged for various other ions, which results in the enlargement of the interlayer distance. [6][7][8] Several studies pertaining to the successful exchange of the H + of the P-OH group in ZP with various divalent and trivalent cations have been reported in the literature. [9][10][11][12][13][14] It has also been reported that ZP possesses excellent selectivity towards Pb 2+ , Zn 2+ , and Fe 3+ as an ion exchanger.…”

Zinc zirconium phosphate (ZPZn) nanoparticles have been used as an efficient catalyst for the selective oxidation of a wide range of alcohols to their corresponding ketones or aldehydes using H 2 O 2 as an oxidizing agent without any organic solvent, phase transfer catalyst, or additive. The steric factors associated with the substrates had a significant influence on the reaction conditions. The results showed that this method can be applied for chemoselective oxidation of benzyl alcohols in the presence of aliphatic alcohols. The catalyst used in the current study was characterized by ICP-OES, XRD, N 2 adsorptiondesorption, NH 3 -TPD, Py-FTIR, SEM, and TEM. These analyses revealed that the interlayer distance in the catalyst increased from 7.5 to 8.7 Å when Zn 2+ was intercalated between the layers, whereas the crystallinity of the material was reduced. This nanocatalyst could also be recovered and reused at least seven times without any discernible decrease in its catalytic activity. This new method for the oxidation of alcohols has several key advantages, including mild and environmentally friendly reaction conditions, excellent yields and a facile work-up.
