An easy yet viable hydrothermal reaction is demonstrated to prepare ultra-small Zn 2 SnO 4 nanoparticle with ~4.2 nm decorated reduced graphene oxide (RGO) nanocomposites (Zn 2 SnO 4 -RGO). The pure phase Zn 2 SnO 4 nanoparticles with ~4.2 nm can be achieved during hydrothermal reaction, meanwhile, these nanoparticles uniformly dispersed on 2D graphene sheet, and graphene oxide was reduced. The photocatalytic performances of the as-prepared Zn 2 SnO 4 -RGO nanocomposites with different RGO mass ratio are investigated. The optimum synergetic effect is found when the RGO mass ratio is 7.11%, with the photocurrent and photodegradation efficiency improved by about 300% and 80% on methylene blue (MB), respectively, compared with the pure Zn 2 SnO 4 nanoparticles. Image 1 • Nano-Zn 2 SnO 4 /Reduced Graphene Oxide Composites were successfully fabricated via an easy yet viable hydrothermal reaction. • The optimum synergetic effect is found at a RGO mass ratio of 7.11%. • The photocurrent response and photodegradation efficiency of Zn 2 SnO 4 -RGO composites were superior to that of pure Zn 2 SnO 4. • The photoelectric and photocatalytic properties of Zn 2 SnO 4 -RGO composites with different amounts of RGO were investigated.
