Abstract
Polyhedral grain-like microparticle Cu0.5Zn 0.5(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 CuZnP2O 7 are verified by XRD data. The presences of the HPO4 2- ion and H2O molecule in the Cu0.5Zn 0.5(HPO4)·H2O structure and the P 2O74- 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.). © 2011 Elsevier Ltd and Techna Group S.r.l.
