Understanding the effect of an amorphous surface on the ultrafast dynamics of a heterogeneous photoinduced reaction: CD3I photoinduced reaction on amorphous cerium oxide films
Abstract:In this work, to understand how an amorphous surface influence the dynamics of surface photoinduced reactions, pump-probe spectroscopy in conjunction with mass spectrometry is employed to track the ultrafast evolution of intermediates and final products with time, mass, and energy resolution. As a model system, the photoinduced reaction of CD3I adsorbed on amorphous cerium oxide films is investigated. A fraction of the first intermediates produced on a freshly prepared surface are trapped to passivate the surf… Show more
