Abstract: Zinc stannate (Zn2SnO4 or ZTO) provides excellent chemical and thermal stability as well as good electrical properties. However, synthesis of fine and homogeneous ZTO nanoparticles is still one of the great challenges. Herein, hydrothermal synthesis of ZTO nanoparticles with the assistance of commercially available additive such as potassium sodium tartrate (PST), monosodium glutamate (MSG) and succinic acid (SA) were investigated. It was found that surfactants play an important role in the formation of cubic spinel ZTO based on powder X-ray diffraction (XRD), which cannot be obtained from the ordinary surfactant-free synthetic processes. In addition, fine and uniform ZTO nanoparticles with average grain size of less than 40 nm in the products from the assistance of PST and MSG were observed by scanning electron microscope. Moreover, Thermogravimetric analysis showed that the weight loss with approximately 7.1 percent, 4.9 percent, and 4.6 percent for ZTO powder obtained from PST, MSG, and SA assisted-hydrothermal synthesis. The weight losses presumably correspond to the presence of surface hydroxyl groups as revealed by Fourier transform infrared spectroscopy. Therefore, we introduce commercially available and low-cost MSG additive to hydrothermally synthesize fine and single-phase ZTO nanoparticles. This nanomaterial should find suitable applications for optoelectronic and energy storage which is a subject of ongoing study.
