Dr. Yating HU: Electrochemical energy storage conversion are important techniques in view of the global energy crisis. My research focuses on developing transition-metal based nanomaterials for electrochemical energy storage and conversion applications, such as electrode materials for supercapacitor and electrocatalysts for water splitting and hydrogen fuel cell. Transition-metal compounds, especially those in the first row (e.g., Fe, Ni, Co and Mn) have been proved to possess high electrochemical and catalytic activities, by both theoretical calculations and experiments. At nanoscale or even atomic scale, the fine tune in material’s morphology, composition and size could have a significant impact on its electrochemical or electrocatalytic activities. My research focuses on studying the formation mechanism of porous structures or nanoparticles of transition-metal based materials. Through novel design and precise control of the material’s morphology and nanostructure at nanoscale, the material’s surface area, electrical conductivity, and air-stability could be largely increased. The strategies I employed include: 1) forming hybrid with carbon to improve the electrical conductivity of transition-metal oxides; 2) soft-template based guided assembly to obtain highly ordered porous nanostructure; 3) using metal-organic framework’s secondary building unit as nano-reactor to derive transition metal nitride nanoparticles on carbon framework.

Dr. Yating HU received both of her Bachelor and Doctoral degrees from the Department of Materials Science and Engineering of National University of Singapore (in the year of 2011 and 2017, respectively). From the year of 2011 to 2012, she worked as a process engineer in solar cell industry. Her research during Ph.D. studies focused on the development of nanomaterials for energy storage application. She mainly used carbon, manganese oxides and iron oxides-based hybrid materials to develop various electrodes for supercapacitors. After obtaining her Ph.D. in 2017, she was a research fellow in National University of Singapore for three years. She joined HKUST as a Research Assistant Professor in 2020. In the past few years, she has developed the guided-assembly method for synthesizing ordered-porous transition metal phosphates. She has also been working on metal-organic framework’s secondary building unit-based nano-reactors to derive functional transition metal/carbon hybrid materials. These materials show attractive application potential in the electrocatalysis for fuel cell and water splitting.
