AI Article Synopsis
- The study focuses on the synthesis of Ag-Cu-Pt-Pd quadrometallic nanoparticles by sequentially adding Pt and Pd to Janus AgCu bimetallic nanoparticles in solution.
- Despite a minor presence of CuO, the resulting nanoparticles consists primarily of separate metallic components rather than an alloy.
- The research highlights that varying the reduction rates of Ag and Cu, along with the sequential addition of Pt and Pd, are essential factors in creating these quadrometallic nanoparticles.
Article Abstract
Ag-Cu-Pt-Pd quadrometallic nanoparticles which small Pt and Pd nanoparticles were attached on the surface of AgCu Janus nanoparticles were firstly synthesized by sequential reduction of Pt and Pd precursor in the presence of Janus AgCu bimetallic nanoparticles as seeds in an aqueous solution. Even though there was a small amount of CuO on the surface, the synthesized nanoparticles were mainly composed of four independent metallic part, not alloy parts. By theoretical calculation and growth mechanism study, we found that different reducing rate between Ag and Cu and sequential reduction of Pt and Pd precursors would be key roles for the formation of the quadrometallic nanoparticles.
