Abstract
A method of upcycling polymers to useful hydrocarbon materials. A catalyst with nanoparticles on a substrate selectively docks and cleaves longer hydrocarbon chains over shorter hydrocarbon chains. The catalyst includes metal nanoparticles in an order array on a substrate.
Claims9
A method of forming a catalyst comprising:
- providing a nanocuboid crystalline substrate;
- forming, by atomic layer deposition, metal nanoparticles arranged in an ordered fashion on the nanocuboid crystalline substrate with an interparticle spacing selected based on a desired hydrocarbon end product chain length;
- wherein the nanoparticles are anchored to the substrate at exposed undercoordinated metal centers of the nanocuboid crystalline structure.
