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.

Card image cap

The most common pollutant in indoor air. Emitted from walls, floors, furniture and cigarette smoke. Confirmed to cause various health problems, and classified as a Group 1 human carcinogen by WHO.

Porous Organic Cages

An emerging porous material, first developed by Professor Andrew Cooper’s research group at the University of Liverpool in 2009. Successfully used in applications including gas storage, gas separation and catalysis.

Designed "molecular trap" for formaldehyde

Cage molecule acts as a "molecular prison" to capture and trap formaldehyde molecules. Each cage molecule can capture 9 formaledhyde molecules, which is 500 times higher than that captured by activated carbon, the most commonly used material for formaldehyde removal.

Customisable cages for different pollutants

Based on the same mechanism, by tuning the size or functionality of the cage molecules, we can develop new materials that capture/detect other emerging indoor pollutants, such as radon (causing lung cancer) or acetaldehyde (one main toxin in smoking).
