I notice in the electroreduction papers, they usually quote yield vs. "current"-- theoretical joules, I suppose.
But most chemists measure yield by how much starting material changed to the desired product. So, by running the electrolysis longer, I get the distinct impression those 60% yields would go up much. Only question is--how much longer? How to tell when it's done? Just guess, say, 20-30% longer, based on hydrogen production? Any ideas?
I like this electrochemistry stuff.

Usually, when they stop the electrolysis before all the starting material is converted, it is because they have found that by-products are formed if they continue. Therefore they rather stop prematurely and recycle the starting material, rather than risk "zapping" any of the desired product formed in the first place.

Seems some experimenting is in order. One of those documents described good results from spongy lead. Maybe like a car battery plate...
