If you want to try this keep in mind the following: The "recipe" I gave doesn't have to be the best, I just experimented a bit. Especially the water content of the carbon has to be taken into account. The drier the carbon is the more water you need to add. Maybe just try this: dry your charcoal as good as possible and then add as much concentrated sugar solution (1500 g/l) as necessary to fill the pores and to get a nice consistency. The amount you add decides over mechanical stability and electrical conductivity of the electrodes.

Clever idea, comrade. I was thinking about just coaling a stick of wood to get a cheap carbon electrode for some electrolyzing experiment with NaCl-brine and free power from a solar panel, so that everything almost costs me nothing. After that, I searched for how to make carbon electrodes and found your surprisingly inspiring video here. No bad idea! Maybe I would just try to use ground barbecue-charcoalpowder and do the similar process and will use some cheap colophonium solved in ethanol for the impregnation. The idea is to produce some NaClO3-solution almost for nothing and after cleaning convert that to KClO3 later. Of course - I have professional equipment already - but am searching for an everybodys way, cheap and easy, you know. You are very creative, and maybe your idea helped me a lot - well done! My additional idea is: protect your electrode inside a fitting steel- or copper-pipe from the air, while glowing the sugar away in a fire, to get less of the coal burned off.

Thanks for your reply! The ratio of carbon and sugar and especially the carbonization process can be improved (holding the electrode together so no holes can form, doing more than one carbonization to reduce pores (comercially done I believe), proper temperature, ...). Of course you're right about the oxygen. Still, I was able to make some nice electrodes, that, as seen in the video, were able to produce chlorine gas. However, I did not try a long run and I wouldn't recommend using resin straight from a tree (as I did) when dealing with agressive chemicals. Either don't impregnate at all, or use something inert. Altough it is important that no metal (like current collectors) comes in contact with electrolyte solution. I did this for fun to see if I could mak a usable electrode from basic materials. I hope it works for you as well!

@StreamMediaSkeptic
2 жыл бұрын
The sugar is basically 50% hydrogen, 25% oxygen, and 25% carbon. Water is comprised of 33% Oxygen and 66% Hydrogen. The short answer is that the Hydrogen and Oxygen burn off leaving only carbon behind which binds the whole thing together. There is a longer explanation of how sucrose is made up of glucose and fructose and that applying heat of x amount of degrees breaks the sucrose back down to fructose and glucose and the continued application of heat equal to y degrees causes these two simple sugars to caramelize and the continued application of heat ..... But it ultimately leads to the same conclusion. Basically, all that remains is carbon gluing all of the individual carbon granules together. Think of it as gluing a steel bar (with jagged edges along the break point) back together by pouring in some liquid steel. Probably not a perfect analogy, but should get the idea across.

After some time you will see the gas coming out the sides of the porous electrode. Correct me if that wasn't what you meant or if you had a different question.

Pencil lead is graphite. This carbon electrode is basically made out of the same material, but the graphite that gives it its conductivity is less structured on the microscopic level.

You would need a proper binder, depending on what you want (should the binder be the material as the electrode?). Don't use PbO2 unless you know exactly what youre doing!

Lation Fly Good question. No, you can directly contact the carbon rod. But since I used it for electrochemestry and it is porous I used an inert current collector (graphite). But you can also just impregnate the top of the electrode with paraffin or some resin and contact this side. Just make sure, that the current collector doesn't come in contact with chemicals (or use graphite/platinum).

It's similar to the way they make them industrially. I just had to find an organic binder material suitable for carbonizing. Sugar was the easiest I could think of and it's nice because sugar is water soluble. I didn't look into any specific literature.

I have tried your method of making electrode but with a different binder. I use a carbon conductive paste, instead of sugar solution, and it doesn't solidify just like what happened to your electrode.

You need a proper ratio of pure carbon and some binder (in my case the carbonized sugar). Maybe just try the recipe of my video or do some tests for yourself. There is certainly a range of ratios and (organic = carbonizable) binders that might work. Industrially, pitch tar is used.

He's not using a proper charcoal kiln, so he has to use the resistance of the sample to determine the purity of the carbon. Not the most precise method, but good enough for what he's doing.

Mad-Eye Sophie-Hattet Not really. Theoretically fluorine and lithium give you the highest voltage but you need special solvents and apparatus to realize it. Fluorine is far too reactive. However you can do it with chlorine if you build my "oxyhydrogen battery" with chloride solution. But the chlorine dissolves slowly, which is why I chose oxygen.

Theoretically. But I think a metal foil will also work. Generally the voltage has to be high enough so that the electrochemical processes can be neglected. If you use this electrode you should impregnate it, because otherwise it will soak up sweat which maybe leads to false measurements.

Marmathic thank you so much for the response! I'm looking for an electrode that will not react to KCl in laboratory, and can be used as conductivity sensor. We used copper on our initial test but it reacts. So I'm looking on using carbon. Is this the better way, or should I look for other materials?
@marmathic9874

The best would be metals like platinum or gold, but they are very expensive ... Carbon doesn't corrode, so its better than copper. But honestly, does it make a huge difference? When dealing with body resistance the current is be so small that it should take a while for the corrosion. I don't know if oxid coated metals might work. Look for "passivation". Thin layers of iron oxide are conductive. The problem with carbon is, that it's not very flexible. Still, chemically it's the best choice.
