Every catalyst particle contains a kind of “road network” over which molecules travel to the active sites in a catalyst. Metals can clog this road network, making the active sites unreachable. A research team from Utrecht University and Stanford has used a new imaging methodology to create a detailed road map of one catalyst particle. This new knowledge will eventually lead to the design of better catalysts for existing or new chemical production processes. The researchers published their results on August 30 in the open access journal Nature Communications.
ARVE Error: Mode: lazyload not available (ARVE Pro not active?), switching to normal mode
Method for creating a road map of a catalyst particle, which includes determining the positions
of the road blocks and simulating the transport of a molecule through the road network,
which may or may not be clogged by impurities.
