Abstract

We report the fabrication of ultrathin aluminum-based overcoats on supported platinum catalysts using atomic layer deposition and hydrid atomic/molecular layer deposition. Tuning the process parameters and applying heat treatment for porosity induction can result to controllably accesible model catalysts. We examined the effect of the number of deposition cycles (1-25), co-reactant choice (water, ethylene glycol, 1,5-pentanediol) and exposure time on the characteristics of the alumina and alucone stabilizing films. The use of fluidized bed reactors for atomic layer deposition applied for active phase deposition and overcoat stabilization paves the way for large-scale gas-phase production of tailored nanostructured catalysts.
