The influence of preparation conditions and doping on the physicochemical and sensor properties of mesoporous tin oxide

The influence of conditions used for preparation of mesoporous materials and thin layers based on tin oxide on physicochemical and sensor properties of these materials were studied. Thermal stability, acidic, sorption and electric properties were studied. The advantage of thin (≈1 μm) thermostable nanocomposite layers with relatively high parameters of the porous structure (V = 0.460 cm3/g, SВЕТ = 440 m2/g) was shown. Obtained materials can be used for selective gas/vapor sensing.
