Towards a laboratory strategy for the study of heterogeneous catalysis in stratospheric ozone depletion

Recent observations suggest that stratospheric ozone depletion over the poles in wintertime may be linked to heterogeneous processes occurring upon low temperature particle surfaces, in addition to homogeneous gas-phase reactions. In situ measurements are difficult, necessitating the development of laboratory methods for I the accurate determination of heterogeneous reaction parameters for a wide variety of atmospheric constituent gases with stratospheric particle surfaces. In this review, some techniques currently being applied to the simulation of representative surfaces and techniques for probing chemistry thereon will be discussed.
