Effect of Mechanochemical and Microwave Modification of SnO₂ Nanomaterials on Properties of Hydrogen Sensors

Tin dioxide was modified via mechanochemical and microwave treatments in order to obtain a mesoporous structure.Samples treated in water possess a thermostable crystal and porous structure.As a result, the samples modified in this way retain a large specific surface area after the manufacture of the sensor.Microwave treatment of SnO2 gel at 270 • C is more promising for the creation of sensitive semiconductor sensors.
