b'Transient SpectrokineticA novel spectrokinetic reactor was developed that couples spectral specificity Reactor to Acceleratewith microkinetic detail to provide researchers with new methods to investigate Development of Advancedfundamental questions of complex materials.Manufacturing Materials M anufacturing essential chemicalsammonia, ethylene, methanol, etc.can be more energy efficient with advanced materials such as catalysts, electrocatalysts, sorbents, and oxidation-reduction agents. These manufacturing processes take place in extreme environments and small changes in conditions can create a large impact on performance. The kinetic performance characteristics (activity and selectivity) of these materials are determined by the composition and structure of a metal/metal oxide surface, a TOTAL APPROVED AMOUNT:fundamental relationship that is not well understood. Thus, operando experiments $167,000 over 2 years where structure is determined in an operating environment are essential. However, PROJECT NUMBER:state-of-the-art operando devices only offer coarse kinetic information and low 20A1047-015 time-resolution on the order of seconds.PRINCIPAL INVESTIGATOR:This research produced a novel spectrokinetic reactor for proof-of-concept Rebecca Fushimi demonstration of transient structural and kinetic characterization of materials. This work was built on the hypothesis that a diffusion reactor, similar to the CO-INVESTIGATORS: TAP reactor, will provide detailed transient reaction data with millisecond time James Pittman, INL resolution while enabling resolution of the surface structural features and adsorbed Yixiao Wang, INL molecules through Raman vibrational spectroscopyinformation that is currently Zachary Thompson, INL not accessible by any one research tool. This uniquely coupled experimental COLLABORATORS: data supports advanced modeling and simulation of materials in the chemical Idaho State University manufacturing process as well as drive predictive tools to accelerate the design and Mithra Technologies Inc. development of materials with advanced performance properties that can reduce the intensity of the highest energy consuming chemicals.100'
