Trends of the anodic ozone evolution reaction are characterized for several different anode material and electrolyte combinations. The effect of electrolyte temperature and concentration, current density, and additions of small quantities of the fluoride ion are explored. The general behavior of ozone current efficiencies are rationalized in terms of coverage of the anode surface by adsorbed anionic material and the electronegativity of the electrolyte anions. At 0°C ozone current efficiencies of over 50% are reported for hexafluorophosphoric acid electrolyte which represent substantially higher yields than any previously achieved.
