Xuanhua Li

        Xuanhua Li received his B.S. degree from Wuhan University of Technology in 2007, and M.S. degree from USTC in 2010. After that, He started his doctoral studies under the direction of Dr. Wallace Choy and received a Ph.D. degree at HKU in 2014. After a short research in the Institute of Intelligent Machines, CAS, he began his career at the Center of Nano Energy Materials, Northwestern Polytechnical University as a professor. His research is focused on synthesis of 2D nanomaterials and novel metal NPs. He is also interested in plasmon-enhanced solar cells, photocatalytic reaction, and optical sensors. He has published more than 30 papers in reputed journals and has been serving as an editorial board member in two SCI journals.

         Hybrid nanostructures composed of graphene or other two-dimensional (2D) nanomaterials and plasmonic metal components are receiving extensive attention. Unusual properties of 2D nanomaterials associated with their ultra-thin thickness and 2D morphology, many interesting structures enable the metal nanomaterials establish many interesting hybrid nanostructures with outstanding plasmonic properties. More importantly, the hybrid nanostructures display extraordinary optical characteristics that are derived from the close conjunction of localized surface plasmon resonance and unique physicochemical properties from two-dimensional materials, as well as the synergistic plasmon-exiton interactions between the two components. They have the potential application for photocatalysis, plasmon-enhanced spectroscopy, photodetector, biotechnology, and solar cells [1]. Here, we will give a talk about our two research. On is about the Au NPs@MoS2 hybrid structures for efficient photocatalytical hydrogen production via strongly plasmonic coupling effect [2, 3]. Another one is about highly intensified surface enhanced raman scattering by using monolayer graphene as the nanospacer of metal film- metal nanoparticle coupling system [4, 5]
