A method for synthesis of platinum nanoparticles by continuous flow using large flow segments. The nanoparticles are monodispersed and can undergo acid leaching to form platinum catalyst, such as PtNi or PtCo catalyst material.

Systems and methods for platinum nanocatalyst synthesis via continuous flow reactor

A method for synthesis of PtNi smooth surface core/shell particles or Nano cages and porous nanocages from segregated nanoparticles.

Control of nanostructure and activity by alloying and/or segregation

A process for synthesis of PtNi high surface area core/shell particles. The processing including formation of PtNi nanoparticles, exposure of the PtNi nanoparticles to oxygen to form a nickel oxide coating on the nanoparticles at the same time the segregation of Ni to surface induces a Pt-skin with PtNi core structure, removal of the nickel oxide coating to form PtNi core/Pt shell (or Pt-skin) structure.

Segregation induced core-shell structure

A synthesis process for forming nanodendrites. The nanodendrites are utilized in a process to form a heterojunction catalyst. Nanodendrites may include PtRunanodendrites that can be oxidized through annealing to form PtRuO. One heterojunction catalyst comprises PtRuOon a carbon support.

Scalable Pt cluster and RuO2 heterojunction anode catalysts

A method for scaled-up synthesis of PtNi nanoparticles. Synthesizing a Pt nanoparticle catalyst comprises the steps of: synthesizing PtNi nanoparticles, isolating PtNi/substrate nanoparticles, acid leaching the PtNi/substrate, and annealing the leached PtNi/substrate nanoparticles, and forming a Pt-skin on the PtNi/substrate nanoparticles.

Systems and methods for scale-up synthesis multi-layered Pt-skin nanoparticle catalysts

A method for synthesis of PtNi nanocages by synthesizing Pt1Ni6 nanoparticles and acid leaching to form PtNi nanocages. The acid leaching removes nickel selectively from the core of the nanoparticle.
