The objective of this research is to develop novel 3D imaging methods for visualizing heterogeneous reactions in situ. Microreaction technology is a viable alternative to conventional catalysis. Advantages include better control of heat and mass transfer, higher surface-to-volume ratio (S/V), reaction efficiency, and less catalyst waste [WAT03]. Due to the small volumes (<1mm3), detailed views inside microreactors are not possible, as inserting sensor probes would perturb the reaction. Consequently, our knowledge of microreactors is limited to simple input/output relationships, making it difficult to optimize a reaction. Operando methodology combines the evaluation of structure and catalytic performance in a single experiment. Current operando methodologies are useful tools to assess the structure-reactivity relationships at a molecular scale via interrogation of the reaction properties. The information gathered can be used in mechanistic studies or for the rational design of improved catalysts.
