Zirconium phosphate is a novel multifunctional mesoporous material and one of the layered solid acid materials. It exists in two structural forms—α and γ—and appears as a white powder that is insoluble in water and organic solvents but resistant to strong acids and moderate alkalis. With a large specific surface area and surface charge, it exhibits strong solid-acid properties and excellent ion-exchange characteristics. As a typical layered compound, zirconium phosphate boasts high chemical stability; it combines the ion-exchange performance of ion-exchange resins with the shape-selective adsorption and catalytic activity of zeolites, while also demonstrating superior thermal stability and resistance to both acids and bases. Consequently, its diverse applications continue to emerge.
Zirconium phosphate (ZrP) is an important inorganic material that has demonstrated broad application potential across various fields. As a multifunctional compound, zirconium phosphate exhibits excellent chemical stability and mechanical properties, making it a research hotspot in numerous industrial and scientific domains. With continuous advances in technology and growing demand, the application scope of zirconium phosphate is expanding and evolving rapidly.
