[NewCandle] Green Acres of Electrodes

[Keith Nagel]

Hi Nick,

The basic scheme of a virtual electrode ought to work.
What kind of meter were you using in your experiments?
I wouldn't expect to see conductivity changes with a DC
type meter, you'd need to look at loss tangent
while exciting the system with HF AC to see the difference.
Moreover, the best results will be had over some
high frequency specific to the experimental particulars.

That said, it's not a big deal to create high surface
area solid electrodes, and one would have the advantage
of being able to apply DC rather than AC. But as Jones
alluded to in his post, one could use semiconductive
particles and see some rectification at the scale
of the particles. 

The question is whether you'd get more H2O2 out than
your energy input, given that you seem to need to
drive the system in some fashion to get meaningful
concentrations of H2O2. It's certainly an intriguing
observation that you get some small percentage of
conversion just by having the catalyst in suspension.
Shades of CF, especially the scaling problem.

But these are questions that have pretty immediate
experimental resolutions. Are you doing that now, Jones?

K.

Hmmmmm!  Fascinating (He says while arching an
eyebrow)

Something seems a bit amiss about the colloidal
electrode idea, though.  No, not amiss... silly choice
of words - personally counter-observational maybe. 
And my observations were VERY limited admittedly...  I
had played with some colloidal gold and iridium when I
had been farting around with Hudson ORME replications
a couple years ago.  Just sticking meter probes into
the liquid showed roughly as high an apparent
resistance as in DI water that I started with.  I
assumed this was due to the VAST capacitance involved.
 And similarly, silver loaded epoxies have to be
loaded to the point where there is a significant
statistical number of grain point contacts for bulk
conductivity.  OTOH, I didn't try injecting high
frequency current into any of it either.  And on yet
another (third?) hand, VAST capacitance could be a
verry good thing!

Somewhere oh somewhere and I think its on my work
puter I have a paper that dealt with using
nanoparticles of Fe3O4 to hydrolize water from maybe
2002.  I'm lounging around home for the next two days
doing my first chemo run, and then back to the lab. 
I'll dig it up then - might be germane.
