"Catalytic reactions on optically excited plasmonic metal nanoparticles"

In has been recognized for some time that strong interaction of electromagnetic fields (e.g., light) with plasmonic nanomaterials offers opportunities in various technologies that take advantage of photophysical processes amplified by this light-matter interaction. More recently, it has been shown that in addition to photophysical processes, optically excited plasmonic nanoparticles can also acti- vate chemical transformations directly on their surfaces. This potentially offers a number of opportunities in the field of selective chemical synthesis.

I will discuss our findings that plasmonic silver nanoparticles, optically excited with low intensity visible light, exhibit direct photo-catalytic activity. I will discuss underlying mechanisms associated with these phenomena. We propose that this new family of photo-catalysts could prove useful for many heterogeneous catalytic processes that cannot be activated using conventional thermal processes on metals or photo-catalytic processes on semiconductors. I will show an example of such a process.

Research interests

The objective of Professor Linic's work is to develop predictive theories of surface chemistry related to heterogeneous catalysis, electrocatalysis and photocatalysis. Researchers in his group are currently working on a number of projects in the fields of sustainable energy generation and conversion, functional nanomaterials, fundamental and applied heterogeneous catalysis. They use a range of experimental techniques including those aimed at performance assessment, kinetic analysis of chemical transformations, in operando spectroscopy, and electron microscopy. These experimental techniques are combined with first principles theoretical tools such as electronic structure calculations (DFT), ab initio kinetics and thermodynamics, and optical simulations.
