Supported Porous Nanoparticles for Functional Plasmonic Materials

The development of renewable energy technologies is crucial for the goal of a global sustainable society. To realize this goals, one key research direction is the development of functional nanomaterials. In this context, metal nanoparticles have shown promise in diverse energy application from, e.g., photocatalyst and hydrogen detection. Noble metal nanoparticles (e.g. gold, silver, palladium) support a phenomenon called localized surface plasmon resonances. Thanks to these resonances, metal nanoparticles are able to efficiently interact with light, e.g., scatter or absorb light much higher than its physical size and localize and amplify the corresponding electric field close to its surface. In particular for the latter, specific design of nanostructures can create the so-called “hot-spots” where the electric field is greatly enhanced. Such nanostructure includes pores in nanostructures. To this end, however, creation of pores in plasmonic particles are limited to colloidally-made particles, and thus they are not attached to a support. Integrating controlled porosity into supported arrays of nanoparticles holds the key for their wide utilization in real devices. Along this spirit, the PlasmoPore project aims to establish a fabrication route to produce supported porous noble metal nanoparticles with highly tuneable physical parameters, by combining wet chemistry and nanolithography, and employ these structures in energy related applications such as hydrogen detection and photocatalysis.

Цел на проекта

Localized surface plasmon resonance (LSPR) occurring in metal nanoparticles has opened the door to the realization of fascinating novel concepts and technologies. This is possible due to the unique properties of the light-metal nanoparticles interaction mediated by LSPR, for example the efficient light absorption and scattering by metal nanoparticles at resonance, as well as enhanced electromagnetic fields in the vicinity of the nanoparticles. A particularly interesting, yet rarely explored nanoparticle feature with great potential for the creation of plasmonic nanostructures with novel functionalities is porosity, which exhibits numerous so-called ""hotspots"": regions where the local electromagnetic field is greatly enhanced with respect to the incoming field. Combined with large surface-to-volume ratios, porous metal nanoparticles offer potentials for e.g. sensing and plasmon-mediated catalysis applications. Despite these prospects, porous nanoparticles have so far been rarely exploited due to the fact that they are produced via colloidal synthesis, which introduces several limitations.The objective of the proposed research is to establish a nanofabrication route, by combining nanolithography and wet chemical route, to produce supported array of porous plasmonic nanoparticles with excellent dimension control and utilize these nanostructures in the fields of plasmon-mediated catalysis and plasmonic hydrogen sensing. The action will combine the researcher expertise in nanofabrication, experimental plasmonics and hydrogen sensing and the supervisor and host institute experiences in wet chemistry, single-particle spectroscopy and plasmon-mediated catalysis. The successful results of this action will contribute to the development of new class of materials, that is supported porous nanoparticles, which extends the library of the functional plasmonic materials with wide applications for example in sensing and plasmon-activated catalysis.""
