Just some brainstorming from someone who is not very knowlegeable about chemistry:

Would electrolysis speed up the dissolving of the copper and getting the reaction you want? Just pass 6.3VAC (more or less, to suit your taste) between two copper electrodes. You get gaseous oxygen (which you apparently want) during part of the electrical cycle, and hydrogen in the other half (so watch out for explosive gas mixture!).

Cheers,
