Photochemistry in Terrestrial Exoplanet Atmospheres I: Photochemistry Model and Benchmark Cases
http://arxiv.org/abs/1210.6885

Study of the photochemistry in terrestrial planet atmospheres dominated by hydrogen, nitrogen or carbon dioxide. Carbon dioxide atmospheres can lead to high ozone levels which may produce false-positive biosignatures.

The distance from the star for the carbon dioxide and hydrogen dominated atmospheres is further out than that for the nitrogen dominated atmosphere with the same surface temperature.
