Talk:Water splitting

Untitled

Of course everyone knows that Hydrogen and Oxygen can be extracted from water given a strong enough electrical current. I've seen claims of people developing more efficient electrolysis methods as well as the use of new metals that can supposedly do the job without any electrical power.

These ideas bring me a lot of hope, given the inevitable energy crisis Oil Crash/Peak Oil. We must find new alternatives in order to maintain our way of life, not to mention reduce the effects of global warming. I'm getting the impression that we might actually be getting closer to the mythical H2O powered car.

A new discovery was made by accident by John Kanzius. Seems that radio waves can now be used to break the molecular bonds in salt water as well. I'm convinced that the use of a few Stirling engines could be used to generate enough electriciy to power the car as well as power the Radio Wave device. Here are a few links for this story.

New Methods

Research

I'm a student in chemical engineering at FSU and one the professors in the department is active in this field. I have read his dissertations and papers on the topic and I added one of his research topics to the page. It involves using defective carbon substrates to effectively produce hydrogen at much lower temperatures.

• I am intrigued but what on earth is a defective carbon substrate! explain! V8rik 17:22, 6 November 2007 (UTC)

• • Basically, a defective carbon substrate is a carbon structure that has minor flaws. The water molecule then is attracted to these flaws and it aids in breaking the water molecule apart. If you want to know more, read the paper (citation 2 on the article page) or contact me on my Talk page. Love to discuss it. :) Daniel Musto 14:53, 7 November 2007 (UTC)

• thanks for your comment but I was really hoping you would be able to write a few lines in the article itself with a brief explanation of defective carbon. After all that is what wikipedia is al about! V8rik 17:52, 7 November 2007 (UTC)

• • Don't worry. I'm working on it. ;) Daniel Musto 18:07, 7 November 2007 (UTC)
• Great! I am looking forward to it. V8rik 18:30, 7 November 2007 (UTC)

Physical

There has been some contentious debate on whether water can be split physically by microwave and RF sources. John Kanzius accomplished this task when he lit a flame above a tube of salt water and initially thought that he was generating more energy than was input. Rustum Roy, a scientist at Penn State University, confirmed that the machine causing the effect indeed generated oxyhydrogen and did not confirm the excess energy Kanzius thought he may have discovered. This process is a topic of research. At Korea's National Fusion Research Center, BongJu Lee has previously communicated that a similar process of water splitting may yield an efficiency up to 84%. The proposed mechanism is dual path via core excitation followed by variations between dissociation & Auger Decay (Sigfusson, T. Phil. R. Trans. Soc. A. 2007, 365, 1025-1042).

It may in fact be the case that in the Kanzius machine enough water dissociated to burn at a sufficiently high enough temperature to aid further dissociation since water will dissociate strongly at the temperature of a pure oxyhydrogen flame. It is not unlikely that such a flame would actually be a plasma. Research has yet to confirm the mechanism as Intramolecular and has not excluded Interatomic Coulombic Decay mechanisms.

Merge

Suggest this article is merged to Hydrogen production as an essentially synonymous term. --Wtshymanski (talk) 22:08, 23 February 2010 (UTC)

Good point, but the term was always a synonymous term for electrolysis of water, Artificial photosynthesis, Photocatalytic water splitting, before it was used as an alternative name, recently like with Photocatalytic water splitting DOE uses it as an umbrella name [[1]] for all methods as long as water is involved. Hydrogen production is not that specific if you make it from Dung, so , I have to oppose the proposal. Cheers Mion (talk) 22:16, 23 February 2010 (UTC)

This gives a better example. [[2]]. Mion (talk) 22:22, 23 February 2010 (UTC)

• Oppose, hydrogen can be produced from other sources than water V8rik (talk) 22:24, 23 February 2010 (UTC)
  • Well then, all the stuff on electrolysis can come out of the "hydrogen production" article and move here. Got to do this, otherwise we'll wind up with just one article on Wikipedia called The sum total of human knowledge to date, which will break old browsers that can't handle pages over 32 k. --Wtshymanski (talk) 14:08, 24 February 2010 (UTC)
    • Hydrogen production is an overview of all existing production methods, which would lack part of the information if you move it out, better to keep it there, where can i find a list of browsers that can't handle 32 k ? thanks. Mion (talk) 19:07, 24 February 2010 (UTC)

Practical uses

The article needs to identify which processes are in regular commercial use, which processes have reasonably near-term expectations of being commercialized, and which processes are at the "PhD Thesis" level or table-top demonstrations with no scale-up to industrial sizes documented. --Wtshymanski (talk) 16:55, 4 March 2010 (UTC)

Is it true this is how fish breath?

Is this how fish breath underwater (getting the oxygen). — Preceding unsigned comment added by 138.38.238.210 (talk) 13:47, 5 November 2013 (UTC) No. Their gills absorb molecular oxygen (O2) dissolved in the water. — Preceding unsigned comment added by Pignut (talk • contribs) 15:53, 9 September 2014 (UTC)

Electrolysis, negative, positive

I'm quite surprised this article does not mentioned which electrode coverts to which chemical. 11:05, 3 February 2016 (UTC)~ — Preceding unsigned comment added by Seb-Gibbs (talk • contribs)
