[edit] Water splitting

One method of hydrogen production is water splitting, the splitting of water into hydrogen and oxygen and one way of doing this uses sunlight. (I reworded this before moving it here.)

How is this relevant to this article? Brian Jason Drake 10:25, 27 November 2005 (UTC)

  • Artificial photosynthesis is not limited to production hydrocarbons from CO2 but includes generating hydrogen from water, see water splitting en reference see for example: http://www.physorg.com/news3122.html. V8rik 17:49, 27 November 2005 (UTC)

[edit] Concept verses reality!

It doesn't seem to me that anybody has succeeded in artificially photosynthesizing CO2 & O2 using natural sunlight! This article in effect describes a concept which is being studied and not a "a man-made process". If someone more informed can give more information then please do, otherwise please re-write this article to reflect the fact that this is only a concept. --DelftUser 07:39, 18 July 2006 (UTC)

[edit] J Read

  • J Read writes in his Text-Book of Organic Chemistry (G Bell & Sons, London, 1935) of a two-stage reaction which, if true as stated, does succeed. He notes that carbonic acid is reduced to formaldehyde in sunlight in the presence of colloidal ferric hydroxide (he credits this step to one "Moore"): H2CO3 -> HCHO + O2. The formaldehyde can then be polymerised to a mixture of hexoses using lime water (Loew 1886 and subsequently Emil Fischer). Nature does not use this method (the "formose" syrup created is a racemic mixture whereas natural sugars are chiral). Dajwilkinson 00:23, 2 May 2007 (UTC)
  • Sounds intriguing but the your reference is old! 1935 or a typo? V8rik 19:44, 2 May 2007 (UTC)
