Graduate Student Chathura Wijethunga in the Chemistry and Biochemistry Department here at Clarkson University will present about Novel Aqueous Phase Synthesis of Ni-Cu Bimetallic Nano-Catalysts at Room Temperature: Metallic nanoparticles offer an excellent foundation for developing tailored catalytic materials because of their structure-function tunability. Controlling the morphology, size and composition is a powerful strategy to optimize the activity, selectivity, and stability of the catalyst. Nickel has been used as a highly efficient homogenous catalyst towards organic reactions with greater reactivity than either platinum or palladium. Incorporating nickel as a foundational material is advantageous due to its cost effectiveness, and inherent ability to enhance catalytic efficacy when incorporated into nanoparticles. Herein we report a protocol for the aqueous phase synthesis of nickel-copper (Ni-Cu) bimetallic nanocatalysts at room temperature, which through intentional disruption of Kirkendall effect on nickel nanoparticles through a thermodynamically favored galvanic exchange process. Moreover, this process results in significant morphology change from spherical to faceted that may be advantageous for the development of a broad range of bimetallic nanocatalysts.
