In this paper ozonation of volatile organic compounds (VOCs) in air has been studied over Platinum catalyst with different surface area, ozone concentration and temperature. Surface and concentration increasing promote removal percent but except the state of free ozone reactions, rising temperature is not so effective. The experiments on new and used catalysts show that catalyst with high surface area (10m2 new Pt), low temperature (50-100°C) and high concentrations (170gr/Nm3) is useful in rising removal percent and energy cost reduction.
