Title: Design and Fabrication of Catalysts for Water-Splitting
Abstract: 
Hydrogen (abundant, clean and renewable) has been considered as one of the most important green energy sources to cater the increasing demand for energy in the future due to the limited supply of the old forms of depletable energy (coal, oil, nuclear) and their detrimental effects on the global climate. Water splitting has attracted increasing attention due to the versatile applications of hydrogen and oxygen gases. Generally, there are two ways for the water splitting, including solar-driven hydrogen production and electrical-driven electrolysis of water. In this talk, I will present our recent work on the hydrogen production using the two methods based on materials’ design and experiment fabrication, including including: (1) Design of photocatalysts for solar-driven hydrogen production. We will present a new concept on the engineering of electronic properties. (2) design and fabrication of two-dimensional (2D) transitional metal dichalcoginides as efficient electrocatalysts for electrical-driven hydrogen production. We showed that the catalytic performance of 2D MLs can be tuned by surface engineering. (3) design and fabrication of doped nanowires as efficient electrocatalysts. We found the doping can dramatically improve the efficiency. (4) Our first-principles design showed that the MXenes can be efficient electrocatalysts for electrolysis of water and co-catalyst in solar-driven water splitting. (5) graphitic carbon nitride with cocatalysts for solar-driven production. The approach enables the enhanced carrier mobility and electron-hole separation, and improved photocatalytic activity in the visible light region and thus offers immense potential for application in solar energy conversion, water splitting, and a variety of solar-assisted photocatalysis.
