题目：Rational design of energy conversion and storage devices
主讲简介：张山青，澳大利亚格里菲斯大学教授。研究专长：生物传感器件的发展及其在能源存储研究。Prof. Shanqing Zhang obtained his PhD degree in electrochemistry in 2001 at Griffith University, Australia. Since then, he has worked as a research fellow during 2001–2006, senior research fellow during 2007–2009 and associate professor at Centre for Clean Environment and Energy and Griffith School of Environment, Griffith University during 2010-2015. As a core inventor, Dr. Zhang has developed a series of patented and commercialized technologies for environmental monitoring based on functional nanomaterials. He was awarded Australia Research Council Future Fellow for 2009-2013. Currently, Prof. Zhang is mainly engaged in the research on synthesis of functional nanomaterials and modification of environmentally friendly natural polymers for energy conversion and storage devices, as well as the development of intelligent online and/or onsite sensors for environmental monitoring. He has published ca. 140 reputable papers and delivered numerous Keynotes and invited lectures.
主讲内容：Photoelectrocatalysis (PEC) is a technique that incorporates electrochemical means to facilitate the separation of the photoelectron-hole produced at photoelectrodes, leading to enhanced photocatalytic efficiency. Due to its inherent advantages of low cost, non-toxicity and chemical stability, titanium dioxide (TiO2) based PEC devices are considered as the most promising system. In this seminar, a series of rational strategies in improving the PEC performance will be introduced: including. conventional nanostructure fabrication, band-gap engineering, the optimization of the PEC reactors in different size, shape, flow channel, optical path and electrochemical system. Large energy capacity, high power density and low cost energy storage device are critical for the electrification of the transportation and energy infrastructures. Silicon-based lithium ion battery and lithium-sulphur (Li-S) battery are the most promising next-generation energy storage devices. My research team attempts to offer promising strategies to silicon anode and sulfur cathode, address the long-standing inherent issues of rechargeable batteries, using modern polymeric binding technology.
