Inorganic Chemistry | ZEPTOOLS ZEM Series Desktop Scanning Electron Microscope Facilitates Research on Room-Temperature Highly Selective Ammonia Sensors
Ammonia has extremely high annual production in fields such as industry, agriculture, and refrigeration, but its strong corrosiveness and acute toxicity pose serious threats to the environment and human health, making the development of efficient gas sensors for real-time monitoring crucial. Gas sensors based on metal oxide semiconductors (MOS), although widely used due to high sensitivity, low cost, and ease of integration, generally face an inherent performance trade-off in practical deployment, namely difficulty in simultaneously achieving high sensitivity, good selectivity, and stable room-temperature operation, and are often limited by relatively high operating temperatures and limited stability under environmental fluctuations.
