WebSep 24, 2008 · In particular, the transition from oxygen chemisorption layer to subsurface oxide formation is quite unexplored at low temperature. The general consensus based on the previous investigations is that oxygen molecules adsorb on Cu(100) via a dissociative pathway with initial sticking probability in a range of 0.01–1 depending on the kinetic ... Dissociative chemisorption. A particular brand of gas-surface chemisorption is the dissociation of diatomic gas molecules, such as hydrogen, oxygen, and nitrogen. One model used to describe the process is precursor-mediation. The absorbed molecule is adsorbed onto a surface into a precursor state.
