Photolysis Extracts Hydrogen

Facebook X LinkedIn Email
VICTORIA, Australia, Aug. 26, 2008 – Hydrogen is the most plentiful gas in the universe and having only one proton, it is the simplest element known to man. As a gas, hydrogen is lighter than air and rises into the atmosphere, which is why it is only found as a compound form with other elements. With hydrogen being touted as the gasoline of the future, the search to obtain pure hydrogen has become the hot topic. It would be ideal to extract hydrogen by splitting water instead of from, say, petroleum, but electrolysis of water is a very energy intensive process, which makes it both expensive and unsustainable if the electricity...Read full article

    anode
    The part of an electrical circuit in which the electrons leave (a cathode-ray tube) or enter (an electrolytic cell) a unit in the circuit.
    cathode
    1. The negative electrode of a device in an electrical circuit. 2. The positive electrode of a primary cell or storage battery. 3. The primary source of electrons in an electron tube, serving as the filament in a directly heated electron tube, and in a coated metal configuration surrounding the heater in an indirectly heated one.
    photolysis
    The photochemical reaction of light present in the decomposition of a substance.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
