Fundamental Investigations of Heterogeneous Catalysis Using Isotopic Transient Kinetic Analysis - (Scope 90001)
EMSL Project ID
18402
Abstract
This project is aimed at developing a new capability at PNNL for performing detailed transient kinetics studies to probe catalytic reaction mechanisms, while simultaneously spectroscopically characterizing the chemical state of the catalyst surfaces. The core capability developed under this project will enable the development of a steady-state isotopic transient kinetic analysis capability to enable a kinetic description of processes to be modeled. Our proposed approach is unique in that we propose an in situ spectroscopic probe of adsorbed reactants/ intermediates/products on the catalyst materials. In principle, the spectroscopic interrogation will enable us to postulate feasible reaction mechanisms, whereas the steady-state isotopic transient kinetic analysis will enable us to test these proposed mechanisms by providing quantitative kinetic rate parameters. Contact Rob Disselkamp, PI, for additional information. Assumption: This project will develop new and unique research capabilities for performing detailed transient kinetics measurements coupled to simultaneous spectroscopic interrogation of heterogeneously catalyzed reactions.
