Our group recently published a research article titled “Catalyst Deactivation by Carbon Deposition: The Remarkable Case of Nickel Confined by Atomic Layer Deposition” in ChemCatChem (Wiley.

The observations arose from a project focused on synthesizing new catalysts for CO2 utilization, & the synthesized alumina-overcoated Nickel catalyst displayed peculiar behavior. This overcoated catalyst resists deactivation even with significant carbon deposited, which would typically deactivate Nickel. This ability is apparently linked to the overcoat’s fracturing by carbon build-up, formation of alumina nano-fibers, and carbon segregation into nano-onions (CNOs).
