    "Photocatalysis is currently one of the hottest topics in science," Menon said. "We expect the present work to have a wide appeal in the community spanning chemistry, physics and engineering."



    be nice if people read more

    convert em and store upon H (dont forget the O)


    now ask the idiots about the btu the recombining offers


    and that is pure basics............

    nuclear reactors are a nice energy source for hydrogen electrolysis as is solar. Also if you heat up water to about 1000 C it splits nicely, so nuclear option again. Issue is the platinum required by hydrogen fuel cells. It is very limited and very expensive.

    Thorium Nuclear power should be the only stepping stone considered.

    temps are for morons


    how about you find out which 'specific wavelength' will separate H and O and use optics. (conversions)

    If this works, it could be a vastly more efficient way of capturing solar energy than PV or CSP. Unfortunately, gallium is rare, so this may not be practical at large scale.

    but are there other structures that can do the same thing? Meaning are there other molecules that can enable the same reaction?

    or are there other molecules that can impose the same wavelength to store (isolate) the H and O?

    I would suggest change the environment (pressure) of the reaction point so the catalyst can combine the energy to enable the reaction.

    Doesn't work that way. You need a material that spans the bandgap between H2 and O2, without too much overage (so that visible light will do the reaction and not, say, UV). AFAIK, this is the first material discovered that's this "perfect" in doing so, and the only other one I know of is also based on gallium.

    funny sheet dude.

    stop the particle thinking.

    look up the "p680" and tell us what the 'bandgap' is.
    do you have a lab?

    P680 asbsorbs at 680 nm, so we can deduce a band gap of 1.82 Ev from Planck's relation. In fact, P680 is being investigated as a dye to sensitize TiO for dye-sensitized solar cells.

    your on a tangent


    'a dye'....................

    the band gap is incapable of describing the "energy state" relation. Ie..... e=hv is not conveying the relation of the actual energy of the pheophytin (chlorophll). Just as the h/o divided are just individual sides of the water with 'energy upon that mass' (their constituent parts)

    the reason i brought that up was because few comprehend that.

    Just because an electron (per se) is not measured does not mean the mass is not sustaining a state of energy (photon).......

    that is the error of the particle model

    It is like YOU want orange (your electron) but cannot comprehend that red and yellow make orange, so to combine the 2 wavelengths you can have your orange.
