| Tartalmi kivonat: | The zinc stannate (Zn2SnO4) is marked as a promising semiconductor material to be used in a field of environmental protection and photocatalysis especially when its band gap is adjusted to enough narrow value to provide its applicability under the visible light irradiation. A traditional solid-state procedure was used to synthesize Zn2SnO4 when a stoichiometrical mixture of starting zinc oxide (ZnO) and tin oxide (SnO2) powders where mechanochemically activated by grinding in a planetary ball mill for 160 min and additionally annealed at 1200°C for 2 h. In this paper, we investigate the most important textural features of the Zn2SnO4 powder for its usage in the photocatalytic degradation of the organic pollutants from wastewaters. Mercury intrusion porosimetry was combined with the scanning electron microscopy to study morphology and surface properties, like specific pore volume, specific surface area, apparent density, and total porosity. |
