Summary, etc. <p>Fabrication of 5 wt% Gd<sub>2</sub>WO<sub>6</sub> doped ZnO via template-free hydrothermal process and its photocatalytic activity against azo dyes, rhodamine-B (Rh–B) and trypan blue (TB) in UV-A light irradiation are reported. The as-prepared Gd<sub>2</sub>WO<sub>6 </sub>doped ZnO has been characterised by X-ray diffraction, field emission scanning electron microscopy, X-ray photoelectron spectroscopy, and, diffused reflectance and photoluminescence spectroscopy. The XRD pattern indicates the distinct diffraction peaks for wurtzite ZnO and body-centered monoclinic structure of Gd<sub>2</sub>WO<sub>6</sub> with good crystallinity. EDS analysis reveals the homogeneous distribution of Gd, Zn, W and O in the prepared catalyst. The results suggests that rare earth tungstate, Gd<sub>2</sub>WO<sub>6</sub> doping on ZnO has great influence on the photocatalytic activity under UV-A light. Gd<sub>2</sub>WO<sub>6</sub>-ZnO possesses high reusability without appreciable loss of catalytic activity up to four runs.</p>
