There is provided a photocatalytic composition building panel that uses solar light to convert atmospheric gas to the output product and capture the output product. The photocatalytic element is encapsulated in a container that is light transmissive, substantially impermeable to atmospheric gases, and substantially impermeable to the product of the output. The photocatalytic element comprises a first component capable of trapping or combining an atmospheric gas, all combined with a homopolymer, a second component capable of reducing the atmospheric gas using energy from the sunlight, And a photocatalytic composition comprising a third component suitable for the following. A fourth component, hydrophobic or hydrophilic, may be added depending on the nature of the other three bound components. |
