Solid solution of trirutile structure type antimonate Zn<sub>1-x</sub>Mg<sub>x</sub>Sb<sub>2</sub>O<sub>6 </sub>(0<u><</u> x <u><</u>1) and its photocatalytic activity is reported here. Compound has been characterized by powder X-ray diffraction and the data confirms the formation of single phasic trirutile products throughout the solid solution. SEM reveals spherical shaped particles with an average particle size of 0.25 – 0.5 µm. EDAX analysis confirms the elemental composition. Raman spectral modes of Zn<sub>1-x</sub>Mg<sub>x</sub>Sb<sub>2</sub>O<sub>6 </sub>characteristic of trirutile structure confirm Mg substitution into ZnSb<sub>2</sub>O<sub>6</sub>. UV – visible diffused reflectance spectra show optical absorption edge in the range of 370 – 318 nm. The band gap in the range of 3.35 – 4.05 eV has indicated the band gap engineering of Zn<sub>1-x</sub>Mg<sub>x</sub>Sb<sub>2</sub>O<sub>6</sub> (0<u><</u> x <u><</u>1) and is explained by electro negativity and band dispersion. All the compositions of Zn<sub>1-x</sub>Mg<sub>x</sub>Sb<sub>2</sub>O<sub>6 </sub>have shown significant photocatalytic activity towards degradation of rhodamine B and it is maximum for MgSb<sub>2</sub>O<sub>6</sub> whose remarkable photocatalytic activity is described here. |
