It might help on a habitat scale, but won't help Mars on a planetary scale. There's simply not enough atmosphere on Mars.
While CO2 makes up 95% of Mars's atmosphere and 0.04% of Earth's. There's roughly the same amount of CO2 in the atmosphere of both planets. There's 500 times as much Oxygen in Earth's atmosphere than CO2. Even accounting for the size difference between the planets, you'd still need hundreds of times more oxygen than the current atmosphere could provide.
