 Abstract:
    Replacement of precious metal catalysts by commercially available alternatives is of great importance among both fundamental andpractical catalysis research. Nanostructured carbon and graphene-based materials demonstrated promising catalytic properties in a wide range of energy generation/storage applications. Specifically engineering graphene and porous carbon with guest atoms can improve their catalytic activity for electrochemical oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thus can be considered as potential substitutes for the noble catalysts
in fuel cells, water splitting to produce hydrogen, or metal-air batteries etc. On such perspective, we have reported graphene-based and other carbon-based metal-free catalysts with a synergistic effect between heteroatoms to boost their electrocatalytic activity. Their electrocatalytic activity and efficiency are comparable with those obtained on the precious metal catalysts. The new catalysts also show excellent long-term stability.

 We will also introduce our other work on functional materials synthesis and their applications on electrocatalytic energy conversion

 Speaker:

 Prof. Shi-Zhang Qiao received his PhD degree in chemical engineering from Hong Kong University of Science and Technology in 2000, and is currently a professor (Chair of Nanotechnology) at School of Chemical Engineering of the University of Adelaide, and an Honorary Professor at The University of Queensland, Australia. His research expertise is in nanomaterials and nanoporous materials for drug/gene delivery and new energy technologies. He has co-authored more than 200 papers in refereed journals (9000 citations with h-index 48), including Nature, Nature Communications, J. Am. Chem. Soc, Angew. Chem., Adv. Mater., and has filed several patents on novel nanomaterials that are promising for drug/gene delivery, fuel cells, photocatalysis, supercapacitors and lithium ion battery.

 Prof. Qiao was honoured with a prestigious  ARC Discovery Outstanding Researcher Award (DORA, 2013), a Emerging Researcher Award (2013, ENFL Division of the American Chemical Society) and a UQ Foundation Research Excellence Award (2008). He has also been awarded an ARC ARF Fellowship, an ARC APD Fellowship and an inaugural UQ Mid-Career Research Fellowship. Professor Qiao is currently an Associate Editor of Journal of Materials Chemistry A and appointed to ARC College of Experts.
