Diffusion and Reaction in Hierarchical Structured Metal Oxides – A Transient TAP Study

Article Preview

Abstract:

Transient TAP measurements have been performed for the first time on nanostructured hierarchical sulfated zirconias prepared by a template-assisted route. The newly designed catalytic materials showed different catalytic activities in the n-butane isomerization. The tailored pore systems had a significant influence on the diffusion properties of reactant and product molecules thus influencing the microkinetics.
