Sputtering deposition of nanoparticles onto liquid substrates: Recent advances and future trends

Catalytically Active Membranelike Devices: Ionic Liquid Hybrid Organosilicas Decorated with Palladium Nanoparticles

“…[20][21][22][23] The sputtering method is quite useful since the size of Pd-NPs can be easily controlled by the current discharge and metal concentration by the time of sputtering. [24][25][26] Moreover, in this method no by-products are generated and only Pd and the support are present in the catalytic material thus allowing a more accurate analysis of the interface Pd-support. Finally, the selective hydrogenation of 1,3-dienes was chosen as a probe to evaluate the properties of the catalysts since this reaction is structure sensitive.…”

Small and uniform Pd monometallic/bimetallic nanoparticles decorated on multi-walled carbon nanotubes for efficient reduction of 4-nitrophenol

“…As for the underlying mechanism, the following process is proposed. The sputtered Pd atoms or clusters in the RTIL coalesce to form small-sized Pd NPs, which are firstly stabilized by the RTIL [14][15][16][17]. The Pd NPs are subsequently decorated onto MWCNTs in the RTIL, as their interaction with the nanosupport is much stronger than that with the RTIL.…”

Temperature-independent formation of Au nanoparticles in ionic liquids by arc plasma deposition

“…In chemical methods, ionic liquids (ILs) are frequently used as the media because prepared NPs which act as catalysts in several reactions are directly produced in ILs, which are expected to be green solvents [4][5][6][7][8][9][10]. In parallel, much attention has been devoted to physical processes combined with ILs as capture media [11][12][13]. In physical methods, atoms, clusters and fragments of metals are ejected by sputtering [14][15][16][17], thermal evaporation [18][19][20] or laser ablation [21,22] from the bulk metal and then land on the surface of ILs and diffuse into the ILs to form NPs without any chemical reactions or additional stabilizing agents.…”
