Advanced Catalytic Material for Air Purification

HKUST
Overview

HKUST developed a supported metal catalyst with nanostructures that can purify air by removing contaminants containing toxic organic, inorganic, and/or biological species in the absence of UV illumination at ambient temperature. The catalytic material is stable and remains active for an extended period of time without the need of regeneration.
