Low-energy cluster or atom beam deposition

Methods for deposition of gold clusters or atoms usually on single crystals or flat surfaces, can also be used for powder supports. For this purpose, the powders are stirred in a rotating device located in front of the cluster or atom beam. 

The other method consists of the sputtering of a high-purity gold target with argon ions, followed by the subsequent deposition of the sputtered gold atoms on the surface of the moving powder support.127 The
