Hydrogen peroxide is water with an extra oxygen molecule. When it is added to water, it sheds the extra oxygen molecule so, for a bit, the water is extra oxygenated. It only takes a drop or 2 and the water needs to be changed daily and the drop or 2 re-added.
If you want to oxygenate the water more efficiently, try an aquarium airstone. That would add oxygen by constanting stirring the water.
