High-performance semiconductor gas sensitive materials are products with independent intellectual property rights developed by the central team. As a semiconductor gas sensing material, metal oxide gas sensing material is widely used in environmental detection and other fields. The center selects tin oxide, zinc oxide, tungsten oxide and other gas sensing materials. Through specific crystal structure control and doping technology, the prepared high-performance semiconductor gas sensing material has high sensitivity and selectivity to hydrogen sulfide, acetone, carbon monoxide, etc.
