Gas sensors with preconcentration
on chemically modified materials
Developed new surface-modified materials
based on nanocrystalline metal oxides and micro / mesoporous molecular
sieves with high selectivity to the major air pollutants and creation
on their basis of chemical sensors. Combining semiconductor gas sensors
and systems for the pre-separation and concentration provides a
significant improvement in the selectivity of semiconductor sensors in
detecting the priority air pollutants H2S, NOx and NH3.
