Scale-up of cluster beam deposition to the gram scale with the matrix assembly cluster source for heterogeneous catalysis (propylene combustion)
Source abstract
Abstract
Cluster beam deposition is a solvent-free method to prepare films of nanoparticles, one obvious application being heterogeneous catalysis. To address the problem of low cluster deposition rates, a novel cluster beam source, the “Matrix Assembly Cluster Source” was invented recently. Following the proof of principle studies, here, we demonstrate a further scale-up by 2 orders of magnitude, equivalent to reaching a production of ∼10 mg of clusters (Au100) per hour. This allows the preparation of cluster-decorated powder catalysts at the gram scale, comfortably sufficient for practical catalysis studies of novel materials at the research level, as demonstrated here by the catalytic combustion of propylene.
