| description | In this study, zinc vanadate/reduced graphene oxide (Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO) composite has been synthesized via a simple approach. Advanced characterization techniques (powder X-ray, scanning electron microscopy, energy dispersive X-ray spectroscopy and ultraviolet-visible (UV-vis) spectroscopy) have been used to authenticate the formation of Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO composite. Subsequently, Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO was applied as photo-catalyst for hydrogen generation using photo-catalysis. The Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO photo-catalyst exhibited a good hydrogen generation amount of 104.6 µmolg<sup>−1</sup>. The Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO composite also demonstrates excellent cyclic stability which indicated better reusability of the photo-catalyst (Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO). This work proposes a new photo-catalyst for H<sub>2</sub> production application. We believe that the presence of synergistic interactions was responsible for the improved photo-catalytic properties of Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO composite. The Zn<sub>3</sub>V<sub>2</sub>O<sub>8</sub>/rGO composite is an environmentally friendly and cost-effective photo-catalyst and can be used for photo-catalytic applications. |
