Pd deposition on TiO2(110) and nanoparticle encapsulation
The effect of sputtering, annealing and oxidation on the surface properties of TiO2(110), and on the same surfaces with nanoparticles present, has been investigated. Sputtering the crystal clean gives a much reduced surface with Ti2þ as the dominant species. This surface is mainly Ti3þ,4 þ after annealing in vacuum. Oxidation reduces the surface Ti3þ considerably. When Pd nanoparticles are anne...
متن کاملNanoparticle Deposition by Boiling on Aluminum Surfaces to Enhance Wettability
Surface wettability of materials is important in a myriad of HVAC&R processes. This study is focused on how to manipulate wettability by nanofluid boiling nanoparticle deposition on aluminum surfaces. The focus is on aluminum, because it is commonly used as the material for heat transfer in air conditioning and refrigeration systems. The boiling deposition process occurs under atmospheric press...
متن کاملMagnetic properties of Pd atomic chains formed during submonolayer deposition of 3d metals on Pd(110).
Recently, an unusual intermixing-driven scenario for the growth of atomic Pd chains on a Pd(110) surface during deposition of 3d metal atoms has been predicted (Stepanyuk 2009 Phys. Rev. B 79 155410) and confirmed by STM and STS experiments (Wie et al 2009 Phys. Rev. Lett. 103 225504). Performing ab initio calculations we demonstrate that Pd atomic chains grown above embedded Fe atoms exhibit m...
متن کاملIn situ encapsulation of Pd inside the MCM-41 channel.
Pd nanoparticles were successfully introduced into the channels of mesoporous silica MCM-41 with their dispersion well-tuned. We identified the dual role played by CTAB, which was critical for both the micelle template and Pd grafting, leading to the formation of a highly active Pd-MCM-41 nanocomposite for catalysing the Suzuki reaction.
