Journal ArticleDOI
Sputtering deposition of nanoparticles onto liquid substrates: Recent advances and future trends
TL;DR: In this paper, the authors discuss the simple and quick method of sputtering deposition over liquid substrates to generate stable colloidal NPs, and some selected results and the current mechanisms of NP formation are discussed.
Journal ArticleDOI
Ionic Liquid Surface Composition Controls the Size of Gold Nanoparticles Prepared by Sputtering Deposition
Heberton Wender,Luciane F. de Oliveira,Pedro Migowski,Adriano F. Feil,Elizeo Lissner,Martin H. G. Prechtl,Sérgio R. Teixeira,Jairton Dupont +7 more
TL;DR: In this paper, the sputtering of gold foil onto 1-n-butyl-3-methylimidazolium tetrafluoroborate, hexafluorophosphate, bis(trifluoromethylsulfonyl)amide, or tris(fluoro)tris(perfluoroethane)phosphate ionic liquids (ILs) generates stable and well-dispersed gold nanoparticles (NPs) of 3−5 nm under conditions of 40 mA, 335 V, and 2 Pa
Journal ArticleDOI
Self-organized TiO2 nanotube arrays: synthesis by anodization in an ionic liquid and assessment of photocatalytic properties.
Heberton Wender,Adriano F. Feil,Leonardo B. Diaz,Camila Silva Ribeiro,Guilherme J. Machado,Pedro Migowski,Daniel Eduardo Weibel,Jairton Dupont,Sérgio R. Teixeira +8 more
TL;DR: The results show that the TiO(2) NTs obtained by anodization in EG/H( 2)O/BMI.BF(4) electrolytes are active and efficient for both applications.
Journal ArticleDOI
Ta2O5 Nanotubes Obtained by Anodization: Effect of Thermal Treatment on the Photocatalytic Activity for Hydrogen Production
Renato V. Gonçalves,Pedro Migowski,Heberton Wender,Dario Eberhardt,Daniel Eduardo Weibel,Flávia C. Sonaglio,Maximiliano J. M. Zapata,Jairton Dupont,Adriano F. Feil,Sérgio R. Teixeira +9 more
TL;DR: In this article, the effect of thermal treatment on the crystalline structure and morphology of Ta2O5 nanotubes was investigated and it was shown that the NTs retained their tubular shape up to 800 °C.
Journal ArticleDOI
Synthesis of gold nanoparticles by laser ablation of an Au foil inside and outside ionic liquids.
Heberton Wender,Marcos L. Andreazza,Ricardo Rego Bordalo Correia,Sérgio R. Teixeira,Jairton Dupont +4 more
TL;DR: The chemical composition of the IL/air interface and surface ion orientation played important roles in the stabilization of the AuNPs formed by laser ablation outside the ILs.
