Shape-Selective Zeolite Catalysis: The Molecular Sieve

Interactive 3D zeolite catalyst simulator: tune the nanopore diameter and watch a molecular sieve admit only reactant molecules narrower than the channel to react at an internal active site, while bulkier shapes are excluded — with a toggle comparing it to an unconfined catalyst surface that reacts indiscriminately.

ControlsZeolite/Unconfined mode toggle buttons switch between the porous sieve and a non-porous catalyst surface; pore diameter slider (0.08-0.60 nm) sets the sieve size cutoff (disabled in unconfined mode); feed rate slider controls how often new reactant molecules are launched; Reset counts button zeroes the per-shape conversion statistics; drag to orbit, scroll/pinch to zoom.

A zeolite particle's rigid, uniform nanopores act as a molecular sieve: only reactant molecules narrower than the pore opening can enter the channel, reach the internal active site, react, and exit as product — bulkier shapes simply bounce off the exterior. Dial the pore diameter to watch selectivity shift between molecular shapes, or toggle to an unconfined catalyst surface that reacts with everything indiscriminately, with no size cutoff at all.
