PhD Studentship Controlled Nanoscale Electrodeposition for Bimetallic Nanoparticle Synthesis

A fully-funded PhD fellowship in electrochemistry is available at University of Cambridge. Successful candidate will have funding to work and study for 3 years in UK. Applications are welcome before December 14, 2018.

Fixed-term: The funds for this post are available for 3 years in the first instance.

Combining the light-harvesting power of plasmonics and the favorable surface chemistry of catalytic metals provides exciting opportunities to create multifunctional NPs that enhance and control light-driven chemistry. Recently, work on new Al/Pd plasmonic-catalysts hybrids has been published [1], followed by the expansion of these solution-based syntheses to 8 different transition metal clusters, providing exquisite composition flexibility for multifunctional nanoparticles [2]. However, these synthetic approaches provide little control over the distribution of catalytic metal on the plasmonic particles owing to their essentially random nucleation and aggregation.

In this project, we aim to use electrodeposition, aka electroplating, as a new nanoscale surface synthesis tools capable of achieving a superior control over surface composition. This will readily provide multifunctionality to nanostructures, for applications in plasmon-enhanced catalysis and beyond. Specifically, metals will be electrochemically deposited onto plasmonic nanoparticles supported on a conductive substrate, and we will study how electrochemical behavior changes at the nanoscale due to undercoordination and plasmonic effects. The optical properties of the particles undergoing this driven electrochemical reaction will be tracked in-situ using single particle spectroscopy [3-4], while the deposition specificity will be analyzed using atomic resolution electron microscopy and spectroscopy.

The results of this work will provide new tools for particle synthesis, as well as new fundamental understanding of will create a new approach to controllably functionalize plasmonic NPs with catalytic metals. In particular, details of how crystallographic orientation and undercoordinated sites (such as corners and edges) affect the surface electrochemical potential in nanoparticles will be unraveled, answering fundamental questions and providing guidance in the design of complex surface composition patterns. The understanding of the surface deposition control achieved with electrochemistry, and of nanoscale effects in electrodeposition, will unlock a new synthetic toolbox for the manipulation and fabrication of multifunctional NPs for sensing and catalysis.

Applicants should have (or expect to be awarded) an upper second or first class UK honours degree at the level of MSci, MEng (or overseas equivalents) and should be eligible for ‘home rate’ fees.
