I made a generator with a copper, a zinc and a silver anode surrounding a stainless steel cathode once. It didn't work.
The only thing I've managed to produce using copper electrodes in a LVDC system in distilled water is a blue/grey precipitate and about a 3 uS conductivity rise after running it for days and days. I know that copper can be plated using low voltages, but the electrolyte had considerable copper sulphate content that had to be replenished now and then. Still, the copper electrodes would wear down, so perhaps the copper electrodes tended to replenish the copper in the electrolyte. It was a long time ago, but I seem to recall using around 48 volts. [You can plate steel with copper suphate without using a power supply at all] I've never seen any reaction at all at 28 volts in distilled water using zinc. I don't remember what the zinc bath electrolyte was made of or what voltage was used to zinc plate things. It was maybe zinc chloride, ammonium chloride or zinc cyanide salts..I don't remember. That was 30 years ago. Just dropping a piece of copper wire into a batch of CS will pull all the silver out of the water and drop it on the bottom as a black deposit in a day or two, without affecting the copper wire. Let us know if the alloy rods work. [I have some doubts, but I've been surprised more than once.] Be also aware that zinc and copper can be very toxic. You need 'enough', but too much is a serious no no. If you do succeed, be very careful. Ode The voltage wasn't high.
