Indoor air pollution


Nowadays, we spend about 70%-90% time indoors. Indoor air pollution causes an estimated 3.8 million deaths worldwide a year, according to a World Health Organisation report. 



Formaldehyde is the most common pollutant in indoor air, which can be emitted from walls, floors, furniture, fabrics and cigarette smoke. Formaldehyde has been confirmed to cause various health problems, and has been classified as a Group 1 human carcinogen by WHO.  

Porous organic cages


Porous organic cages (POCs) are an emerging porous material, first developed by Professor Andrew Cooper’s research group at the University of Liverpool in 2009. POCs have been sucessfully used in applications including gas storage, gas separation and catalysis.
