Combinatorial Operando Catalyst Research
EMSL Project ID
25401
Abstract
This is the continuation of EMSL proposal 21610. The main objective of this proposal is to build and demonstrate a combinatorial operando system for accelerated catalyst research. This system will be the first of its kind. It integrates FTIR and Raman imaging techniques jointly to a combinatorial reactor assembly for real time full product analysis and material characterization under operating conditions. The system takes advantage of the powers of (1) Raman imaging to obtain mechanistic understanding of catalytic reactions on catalyst surfaces by characterizing the adsorbed molecule-catalyst interaction, reaction precursor/intermediate states, and site structural variations; (2) FTIR imaging for rapid product analysis, and (3) a unique high throughput reactor assembly capable of evaluating multiple catalysts simultaneously. The FTIR imaging system will output at least 128x128 spectroscopic pixels every 2-seconds. It is applicable to both gas/solid and liquid/solid processes. A mass spectrometer will also used for product confirmation. High chemical specific Raman spectroscopic measurements combined with IR imaging provide unique and crucial characterization of catalytic reactions. Statistical experimental design software will be in conjunction with the combinatorial operando catalyst research (COMBOCARE) system to allow for the design of critical experimental matrices and for optimization of process parameters. Informatics that correlates catalyst performance and catalyst structural details will also be developed.
