Abstract

(Figure Presented) Shedding light on catalysis: For the first time, transport phenomena and their influence on catalysis are directly observed for individual catalytic particles by single-turnover mapping using highresolution fluorescence microscopy. The Thiele modulus could be measured with just one experiment, proving the existence of diffusional limitations for the Ti-MCM-41 catalyzed epoxidation of a fluorescent reporter molecule (see picture; TBH P = tert-butylhydroperoxide).
