Simple fabrication of polyhedral grain-like microparticle Cu0.5Zn0.5HPO4·H2O and porous structure CuZnP2O7

Polyhedral grain-like microparticle Cu0.5Zn0.5(HPO4)·H2O was simply synthesized by heterogeneous reaction using a mixture of CuCO3, ZnO, phosphoric acid and water at room temperature for 30 min. The thermogravimetric study indicates that the synthesized compound is stable below 250 °C and its final decomposed product is CuZnP2O7. The pure monoclinic phases of the synthesized Cu0.5Zn0.5(HPO4)·H2O and its final decomposed product CuZnP2O7 are verified by XRD data. The presences of the HPO42− ion and H2O molecule in the Cu0.5Zn0.5(HPO4)·H2O structure and the P2O74− ion in the CuZnP2O7 structure are confirmed by FTIR data. The thermal stability, the morphology based on polyhedral grain-like microparticles and porous structure of the studied compounds are different from previously reported phosphates, and may affect their activities for potential applications (catalysis, electronics, etc.).
