Ozone decomposition on Saharan dust : an experimental investigation

  title={Ozone decomposition on Saharan dust : an experimental investigation},
  author={Frank Hanisch and Joseph N. Crowley},
The heterogeneous reaction between O 3 and authentic Saharan dust surfaces was investigated in a Knudsen reactor at≈ 296 K. O3 was destroyed on the dust surface and O2 was formed with conversion efficiencies of 1.0 and 1.3 molecules O2 per O3 molecule destroyed for unheated and heated samples, respectively. No O 3 desorbed from exposed dust samples, showing that the uptake was irreversible. The uptake coefficients for the irreversible destruction of O 3 on (unheated) Saharan dust surfaces… CONTINUE READING
