Abstract

Zn- Pb- Zr ternary intermetallic phases were synthesized by high-temperature solid-state synthesis. Structural characterization was performed by means of powder X-ray diffraction and energy dispersive X-ray analysis. X-ray powder diffraction coupled with Rietveld refinement reveals the sample’s phase purity we have prepared. Thermal behavior analysis shows Zn_0.61 Pb_0.91Zr_0.138 is very stable, it doesn’t decomposition until heated up to 998 °C. UV-visible absorption and diffuse reflection spectrum feature characteristic absorption bands of d-electron transition and main group metallic alloy given an optical band gap value of 3.65 eV. Magnetic susceptibilities measurement gives significant anti- ferromagnetic interactions between magnetic centers. The results further encourage the prospects of ternary Zn-Pb-Zr alloy anodes to utilize in real energy storage applications The photo degradation experiment were performed to evaluate photocatalytic activities of Zn0.61 Pb0.91 Zr0.138 .The Rietveld refinement parameters are a=8.731(Å),b=8.734(Å),c=5.929(Å), GOF=1.214,Rwp=31.21,Rp=21.321 having hexagonal crystal system with primitive . P 63/m c m space group.
