Professor Jin Shang’s Team Achieves Breakthrough in Sustainable NO₂ Capture in Nature Communications

Congratulations to Dr. Zeyu Tao, Postdoctoral Researcher in Prof. Jin Shang’s group at the School of Energy and Environment (SEE), City University of Hong Kong (CityUHK), and former MSc and PhD student, on the publication of his research paper “Complete ambient-temperature NO₂ removal by mature zeolite adsorbents via a cooperative adsorption mechanism” in Nature Communications.

The study revisits Linde Type A zeolites, mature adsorbents that have been widely used in industry for more than 70 years and uncovers the fundamental physical chemistry enabling a capability long considered unattainable.

The team reports the first adsorption-based technology to achieve complete ambient-temperature NO₂ removal with zero NO emission, offering a scalable and sustainable solution to one of the most persistent challenges in air-pollution control.

Prof. Shang emphasized that this breakthrough demonstrates the importance of re-examining established materials to address modern environmental and sustainability needs, while highlighting the strength of combining deep physical-chemistry insights with adsorption science.

This achievement reinforces CityUHK’s leadership in adsorption-based gas separation research and its commitment to advancing clean-air and sustainability technologies with global impact.
