主讲人简介: Dr. Wei-Hsiang Huang obtained his PhD at National Taiwan University of Science and Technology (NTUST) in 2022 on the synchrotron XAS techniques of energy materials studies. Since 2023, he is a beamline scientist at the National Synchrotron Radiation Research Center (NSRRC) TPS44A Quick-Exafs beamline. His main research interests focus on Quick-Exafs analysis and in-situ/operando development of 2D materials, single-atom catalyst and battery system. For now, he has more than 70 articles published in scientific journals.
报告内容简介: Developing more advanced in situ or in operando characteristic techniques for gauging the kinetic and dynamic evolution of electronic structure, phase, interfacial phenomena, strain and morphology as well as catalytic reaction mechanisms of energy materials under the operation of electrochemical reaction or synthesis conditions is crucial and inevitable to the future study. Main topics including the interfacial phenomena of strong metal-support interaction (SMSI), in situ reactions, and the catalytic energy conversion reaction (ECR) and fading mechanisms of nano-catalysts for fuel cells and water splitting application are addressed. Recent advances in the application of in situ/operando techniques for characterization of SACs including Transmission Electron Microscopy (TEM), Spherical Aberration Corrected Scanning Transmission Electron Microscope (Cs-corrected STEM) and Quick X-ray absorption spectroscopy (Quick-XAS) has applied to single-atom system as an advanced technique for capturing the reaction dynamics, distinguishing the metal active sites and more in-depth electronic state of the catalytic at atom scale.
