Oriented catalytic platinum nanoparticles on high surface area strontium titanate nanocuboids.
نویسندگان
چکیده
Platinum nanoparticles grown on SrTiO(3) nanocuboids via atomic layer deposition exhibit cube-on-cube epitaxy with the predicted Winterbottom shape, consistent with literature values of the interfacial and surface free energies. This thermodyamically stable configuration should survive the rigors of catalytic conditions to create stable, high surface area, face-selective catalysts.

Nucleation and growth process of atomic layer deposition platinum nanoparticles on strontium titanate nanocuboids.
Uniform, well-dispersed platinum nanoparticles were grown on SrTiO3 nanocuboids via atomic layer deposition (ALD) using (methylcyclopentadienyl)trimethylplatinum (MeCpPt(Me)3) and water. For the first half-cycle of the deposition particles formed through two sequential processes: initial nucleation and growth. The final particle size after a single complete ALD cycle was dependent on the reacti...
متن کاملControllable ALD synthesis of platinum nanoparticles by tuning different synthesis parameters
Pt nanoparticles were successfully deposited using three different atomic layer deposition (ALD) methods, e.g. ABtype, ABCtype and static ABCtype ALD, on two different types of strontium titanate nanocuboids (STONCs) samples in a reaction temperature window of 125 °C–300 °C. The influence of reaction temperature, number of ALD cycles, type of substrate, 2nd reagent and type of ALD method on...

متن کاملGrowth of arrays of oriented epitaxial platinum nanoparticles with controlled size and shape by natural colloidal lithography
We developed a method for production of arrays of platinum nanocrystals of controlled size and shape using templates from ordered silica bead monolayers. Silica beads with nominal sizes of 150 and 450 nm were self-assembled into monolayers over strontium titanate single crystal substrates. The monolayers were used as shadow masks for platinum metal deposition on the substrate using the three-st...
