Reactive scattering of CO from an oxygen-atom-covered Au/TiO2 model catalyst
Article Abstract:
The main aim of the study is to gain some insight into the microscopic-level details regarding the CO oxidation reaction on titania-gold catalysts. The results show that the reaction of an oxygen atom with CO is relatively particle size independent and even independent of the TiO2 support and therefore not exclusive to the gold-titania interface, if oxygen atoms are preadsorbed prior to CO exposure.

Reactivity of molecularly chemisorbed oxygen on a Au/TiO2 model catalyst
Article Abstract:
Results of an investigation into the reactivity of molecularly chemisorbed oxygen with CO on a Au/TiO2 model catalyst at 77 K are presented. Samples that are populated with both species consistently result in greater CO2 produced than samples with only atomic oxygen.

Dynamic effectiveness factor for catalyst particles
Article Abstract:
A dynamic effectiveness factor (DEF) concept that extends the existing nondynamic one is introduced. The effectiveness factor is a nondynamic concept that is demonstrated to be useful for the analysis and design of reaction-diffusion systems.
