Kinetics of the heterogeneous reaction CO+ O -> CO2 on inorganic oxide and water ice surfaces: Implications for the Martian atmosphere

By Wonyong Choi and Ming-Taun Leu


this article we report the reaction probability measurements of the heterogeneous CO + O recombination (reaction 4) on water ice and various inorganic oxides substrates, which mimic the Martian aerosol materials, using a fast flow-tube reactor coupled to a quadruple mass spectrometer. First we will present the experimental apparatus and data analysis; then we will discuss the measurement of the values. Finally, we will compare both homogeneous and heterogeneous processes (reactions 2-4) potentially important for maintaining the stability of C0 2 in the Martian atmosphere. 3 Experimental Metho
