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.
