Surface modification of Al2O3 ceramic grains using a new RF sputtering system developed for powdery materials

CO oxidation on non-alloyed Pt and Ru electrocatalysts prepared by the polygonal barrel-sputtering method

“…The present authors have developed a new surface-modifying dry process named as the "polygonal barrel-sputtering method" [24][25][26][27][28][29][30]. Recently, we reported the preparation of electrocatalysts for PEFCs using this method [29,30].…”

Surface Modification of Fine Particles with a SnO2 Film by Using a Polyhedral-Barrel Sputtering System

“…We have recently developed polyhedral-barrel sputtering system that can be used to modify fine particle surfaces with a metal or alloy in a dry process [10][11][12]. Compared with wet processes such as plating, sputtering has the advantages of being less prone to infiltration of impurities, offering a wider range of choices of modification materials, and carrying a lower environmental burden.…”

Carbon Oxidation Reaction over Pt/Spherical Alumina Beads Catalysts Prepared by Sputtering Method

“…They found that the Au particles deposited by sputtering were more active for glycerol oxidation than those prepared using the PVA sol. The sputter deposition method has been reported to give uniform dispersion of metal on support; for example, Pt on Al 2 O 3 [7,8], Pt-Ru on carbon [9], Cu on SiC [10], and Au on Al 2 O 3 [11]. Such a sputter deposition method has been hardly used for the synthesis of supported catalyst because of highly expensive compared to impregnation method.…”
