Title

Surface Deactivation Efficiencies for O₂(¹Δ)(g) on a Range of Materials I. Pyrex, nickel, copper, nickel-copper alloy and inconel

Abstract

A kinetic model is presented that describes both homogeneous (kq) and heterogeneous (γ) deactivation of O2 (1Δ)(g) in a flow reactor experiment. The model is validated through measurements made on Pyrex surfaces where kq and γ were found to be (1.6±0.4)×10-18 and (3.1±0.2)×10-5 cm3 s-1 respectively. The model has been used to interpret data recorded for aged surfaces of the following metals: nickel γ= (3.2±0.2)×10-4, copper γ= (2.9±0.2)×10-4, 10 90 nickel-copper alloy γ= (2.8±0.2)×10-4, and inconel γ= (1.2±0.2)×10-4.
