Lecture Title: Defectsin metal oxide for energy conversion and storage application

Abstract

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. OV in titania and lithium titanate  nanomaterials achieved via hydrogenation, chemical reduction and cold quenching  are 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.

Biography

Prof. Eddie 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 design  and synthesis of functional nanomaterials and polymers (binders and solid  polymeric electrolyte) 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. 160 reputable papers with H-index of 50and  delivered numerous Keynotes and invited lectures.
