Nano Surface Science and Engineering for Energy Conversion and Diamond Transistors
Electron Energy Loss Spectroscopy (EELS) measurements of plasmon resonances of Au-MgO nanostructure to be applied for water splitting References Z. Liu, et. al., 2018 under submission.
Nano science and technology offer a vast and fascinating playground
to explore the novel physiochemical properties of nanomaterials with the development for various applications including energy conversion and electronics.

In this talk, I will present the recent investigation on the surface chemistry and physics and their effects on the nanoscale electro/photo-catalysis and diamond-based surface charge doping, such as surface molecular tunable crystal phase engineering with two-dimensional (2D) WS2 towards stable electrocatalytic hydrogen evolution reaction, surface oxygen vacancies from MgO porous nanoparticles for stable photocatalytic water splitting with gold’s local plasmonic further enhancement; and hydrogenated MoO3 layer as a novel efficient sustainable surface charge acceptor for diamond transistors. These surface science and engineering enable the enhancement of functional efficiency and the extension of performance stability in electro/photo-catalysis and electronics. This talk highlights the synergistic surface science and engineering can provide the opportunities to customize nanomaterials for advanced applications development.
