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.
