Johnson Matthey, the Seeker for this Challenge, manufactures nickel-aluminum (Ni-Al) material via a cast and crush. This produces high surface area nanoporous nickel (Ni) sponge particles after removal of the aluminum (Al) by leaching. Primarily used as a hydrogenation catalyst, Johnson Matthey seeks new and innovative uses for this material.

This is an Ideation Challenge with a guaranteed award for at least one submitted solution.
Nanoporous particles exhibit a tremendous amount of surface area for a small amount of material and are quite useful for surface-dependent processes such as heterogeneous catalysis. Johnson Matthey, the Seeker for this Challenge, produces nanoporous nickel (Ni) sponge particles through a cast and crush method utilizing a nickel-aluminum compound and subsequent removal of the aluminum (Al) through leaching. The particles are formed by milling larger blocks of material which produces particles that are jagged in shape and on the order of tens of microns in size but can be produced in a wide variety of sizes through the milling process. Typical pore diameter is 5.0-6.5 nanometer and surface area is 70-85 m2/gram.
Johnson Matthey also can dope the material with elements such as palladium, chromium, and molybdenum as well as potentially with other metals and non-metals. This material is primarily used as a hydrogenation catalyst but could potentially be used in many different ways. Johnson Matthey is seeking new and innovative uses for this material. They would like information on potential market size for new uses and technical details of utilizing the material in new applications.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on 28-Nov-2022.
