The research aims to explore the growth of alumina overlayer on a specific catalyst model using atomic layer deposition.
Utilized atomic layer deposition technique for alumina growth
Investigated agglomeration behavior of metal clusters on Au/TiO2
Analyzed size-dependent electronic properties of the resulting catalyst
Found that alumina overlayer effectively reduces agglomeration of metal clusters
Observed maintenance of unique electronic properties due to minimized agglomeration
Demonstrated size-dependent characteristics retained in the catalyst model
Abstract
A major challenge in maintaining the unique, size-dependent properties of metal clusters arises from their tendency to agglomerate after deposition, which leads to the loss of their unique electronic and...
