Oxygen producing metabolism

What kind of realistic oxygen producing reaction used by life could exist in a carbon dioxide / ammonia atmosphere? There are also many volcanoes, either immersed or not, water oceans and you can even use silicon oxides or whatever from the crust of my Earth-like planet. The further it is from our actual photosynthesis the better it is, but it still has to be likely.

Note: I know ammonia will react with oxygen as it did on Earth. That is actually the purpose of these organisms.
