Atmospheric Environment Monitoring and Pollution Controlling
HFIPS has established a new interdisciplinary of environmental science and technology by integrating and merging subjects of nano and biology science and technology into the original preponderant discipline of atmospheric environmental optics.
After more than four decades of development, HFIPS has built the Integrated Ground-to-Space System for monitoring and early-warning to respond to nation’s challenge in environment issues through its scientific excellence in diversified branches in the field of environmental science and technology, including fundamental research, equipment development, and industrialization.
For environment protect, HFIPS takes its role by using nano-material research to detect and remove pollutants as well; fabricating catalyst to treat hard-to-degrade and high concentration industrial waste water; building monitoring and early-warning network based on nano-sensor and satellite positioning technology.
With the rapid development of industrialization and urbanization, large amount of volatile organic compounds (VOCs) have been emitted into the atmosphere, causing serious air pollution. VOCs monitoring，like metal oxide semiconductor VOCs sensor, is usually small and low-cost. However, poor selectivity, especially for VOCs molecules, is the bottleneck that limits its applications. A research group led by prof. MENG Gang conducted a series of study on VOCs molecule recognition. Important breakthroughs were made recently. The expanded NiO based sensors and smart recognition system, which was constructed by thermally modulated metal oxide sensors, realized successful discrimination of multiple VOCs with similar structure and properties.
Nitrous oxide (N2O) and carbon monoxide (CO) play important roles in global warming. However, there are many difficulties in reliable long-time monitoring, especially for N2O, as the concentration of N2O in atmospheric is only a few hundred part per billion, while the compatibility precision is 0.1 part per billion recommended by World Meteorological Organization (WMO).
Atmospheric parameter sounding is a necessary input parameter and a reference for atmosphere and environmental protection departments to master the atmospheric conditions, conduct atmosphere and air quality forecasting and formulate corresponding emergency control strategies.
