Photohydrogen — is hydrogen produced with the help of artificial or natural light This is how the leaf of a tree splits water molecules into protons (hydrogen ions), electrons (to make carbohydrates) and oxygen (released into the air for us to breathe) [… … Wikipedia
Photoelectrochemical cell — Photoelectrochemical cells or PECs are solar cells and extract electrical energy from light, including visible light. Each cell consists of a semiconducting photoanode and a metal cathode immersed in an electrolyte. Some photoelectrochemical… … Wikipedia
Photodissociation — Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons. Photodissociation is not limited to visible light, but to have enough energy to break up a molecule, the photon is … Wikipedia
Photochemical logic gate — A photochemical logic gate is based on the photochemical intersystem crossing and molecular electronic transition between photochemically active molecules, leading to logic gates that can be produced. The OR gate Electron / Photon transfer chain… … Wikipedia
Biological hydrogen production — is done in a bioreactor based on the production of hydrogen by algae. Algae produce hydrogen under certain conditions. In the late 1990s it was discovered that if algaeclarifyme are deprived of sulfur they will switch from the production of… … Wikipedia
Photofermentation — is the fermentative conversion of organic substrate to biohydrogen manifested by a diverse group of photosynthetic bacteria by a series of biochemical reactions involving three steps similar to anaerobic conversion. Photofermentation differs from … Wikipedia
