A gas absorbing mineral polymer such as a metakaolin-based mineral polymer prepared from a mixture comprising 20 to 30% metakaolin by weight. Preferably, the gas absorbing mineral polymer is a foamed mineral polymer comprising a porous structure of voids on the millimetre or nanometre scale, in diameter. Preferably, the gas absorbing mineral polymer is capable of absorbing gases such as nitrogen oxide (NO) and nitrogen dioxide (NO2), carbon dioxide (CO2) and/or sulphur dioxide (SO2) from the surrounding atmosphere. The mineral polymer material may be formed into different shapes for products or parts of products such as a building material, a building, an item of furniture, a combustion engine, a vehicle, a ventilation system or a respiratory device. |
