Microwave assisted synthesis of nanocomposites in Zn-Sn-O-Ag system and their photocatalytic activity

The crystalline Zn2SnO4 Zn2SnO4/Ag and ZnO-Zn2SnO4 nanoparticles with specific surface area in the range of 24.1-28.5 m2/g were prepared by combining microwave assisted synthesis with additional calcination at 900 °C. The parameters of the powders were compared with those of ZnO and ZnO/Ag nanoparti...

Description
Summary:The crystalline Zn2SnO4 Zn2SnO4/Ag and ZnO-Zn2SnO4 nanoparticles with specific surface area in the range of 24.1-28.5 m2/g were prepared by combining microwave assisted synthesis with additional calcination at 900 °C. The parameters of the powders were compared with those of ZnO and ZnO/Ag nanoparticles prepared by microwave synthesis at 150 °C. The crystallite size of oxide and silver nanoparticles was in the range of 30-52 nm and 18-60 nm, respectively, depending on composition. The prepared nanoparticles showed high photocatalytic activity in degradation of methylene blue under ultraviolet and sunlight irradiation.
