1. A catalyst comprising:
a perovskite substrate; and
a plurality of ordered metal nanoparticles, having an average size of 5 nm±4 nm, anchored to the perovskite substrate at exposed undercoordinated metal centers of the perovskite substrate;
wherein the plurality of ordered metal nanoparticles are configured for an interparticle spacing corresponding to a desired hydrocarbon fragment product of a catalyzed polymer hydrogenolysis reaction; and
further wherein the plurality of ordered metal nanoparticles are anchored to the exposed undercoordinated metal centers at distances selected from the group consisting of ˜20 Å, 14 Å, 9.8 Å, and 3.4 Å.
