Zeolites catalyze the petroleum refining process that produces the majority of the world’s gasoline. The catalytic prowess of these porous solids emanates from aluminum atoms sprinkled throughout their silicate frames. Until now, researchers have struggled to determine precisely where the aluminum atoms reside.

By using atom probe tomography (APT), a relatively uncommon technique that maps elements in three dimensions, an international team of researchers has pinpointed the locations of aluminum atoms in a commercial zeolite . . .
