Provision of oxygen is of vital importance if human stays at outer space for a long period of time. Julian Melchiorri, an engineering graduate of Royal College of Arts succeeded in developing the world’s first artificial leaf, which can provide astronauts with oxygen through the process of photosynthesis.

Natural plants cannot grow under the environment with zero gravity, but fibroin can. To develop an artificial leaf, chloroplast has to be extracted from plants and put into fiboin. An artificial leaf can absorb water and carbon dioxide, as well as carry on photosynthesis under the sun to produce oxygen, just like natural green leaves.

It is predicted that artificial leaves can be applied on the biochemical air supply system so that fresh air with high oxygen content can be provided indoors.
