报告摘要：
Oxygen vacancy (OV) can be considered as a defect when the number of oxygen atoms expected in a compound is less (or missing) than what it should be in its perfect crystal lattice, it is known as In this talk, OV in titania and lithium titanate nanomaterials achieved via numerous ways (hydrogenation, cold quenching and chemical reduction) is characterized and applied for photocatalysis and lithium ion battery applications. The preliminary results suggest that the OV could bring about significant enhancement in energy conversion efficiency and energy storage capability and stability.

个人介绍：
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. 150 reputable papers and delivered numerous Keynotes and invited lectures.
