Abstract
A catalyst for decomposing a plastic includes a porous support having an exterior surface and defines at least one pore therein. The catalyst also includes a depolymerization catalyst component disposed on the exterior surface of the porous support for depolymerizing the plastic. The depolymerization catalyst component includes a Ziegler-Natta catalyst, a Group IIA oxide catalyst, or a combination thereof. The catalyst further includes a reducing catalyst component disposed in the at least one pore. The catalyst is formed by a method that includes the step of disposing the depolymerization catalyst component on the exterior surface. The method further includes the step of disposing the reducing catalyst component in the at least one pore.

A catalyst for decomposing a plastic, said catalyst comprising:
- a porous support having an exterior surface and defining at least one pore therein;
- a depolymerization catalyst component disposed on said exterior surface of said porous support for depolymerizing the plastic, said depolymerization catalyst component comprising a Ziegler-Natta catalyst, a Group IIA oxide catalyst, or a combination thereof;
- and
- a reducing catalyst component disposed in said at least one pore.
A method of forming a catalyst comprising a porous support having an exterior surface and defining at least one pore therein, a depolymerization catalyst component disposed on the exterior surface of said porous support for depolymerizing the plastic, the depolymerization catalyst component comprising a Ziegler-Natta catalyst, a Group IIA oxide catalyst, or a combination thereof, and a reducing catalyst component disposed in the at least one pore, said method comprising the steps of:
- disposing the depolymerization catalyst component on the exterior surface;
