Scientists discovered reversible fragmentation in platinum catalysts using cerium oxide, potentially improving stability and recyclability.
Scientists at Brookhaven National Laboratory, Stony Brook University, and collaborators discovered new details about reversible platinum catalyst assembly. Single platinum atoms aggregate on a cerium oxide surface under reaction conditions, forming active catalytic nanoparticles that fragment when the reaction stops. This reversible fragmentation could improve catalyst long-term stability and recyclability.
