Abstract:
The operando molecular spectroscopy methodology was introduced after 2000 and is rapidly making significant inroads into the fundamental understanding of heterogeneous catalysts for many applications. Operando spectroscopy refers to the simultaneous collection of catalyst spectroscopic information (catalytic active sites, surface reaction intermediates and bulk structure) and online analysis of reactants and products (kinetics and selectivity). These unprecedented molecular and electronic insights are allowing for establishment of catalyst structure-activity/selectivity relationships and are guiding the rational design of advanced catalysts. Several catalysis examples will be presented (olefin metathesis, olefin polymerization, water-gas shift, biomass pyrolysis, and methane to liquid aromatics).
