Morphological, Structural, Substructural Characteristics and Chemical Composition of Zn2SnO4 Nanoparticles

The work synthesized zinc stannate nanoparticles using KOH solution as a mineralizer by the hydrothermal method. The synthesis time t
s
was varied from 16 to 32 hours with an interval of 4 hours. Morphological, structural (lattice period, unit cell size), and substructural (size of coherent scattering regions, level of microdeformations, dislocation density) characteristics of nanoparticles and their chemical composition were studied. It was established that the particles obtained at t
s
= 16 h contained a mixture of phases, while the other samples were single-phase with a cubic structure of inverse spinel Zn
2
SnO
4
. As a result of the research, the temperature and time of synthesis of Zn
2
SnO
4
nanoparticles were optimized.
