报告人简介: Prof Chuan Zhao is currently at the School of Chemistry at The University of New South Wales (UNSW), based in Sydney, Australia. Prof Chuan Zhao is currently the Chairman of the Royal Australian Chemical Institute (RACI) Electrochemistry Division, and also the Chairman of the 4th Asia-Pacific Conference on Ionic Liquids and Green Processes / 6th Australasian Symposium on Ionic Liquids. He received his PhD in 2002 with an excellence award from Northwest University. He then completed 4 years of postdoctoral research at the University of Oldenburg. In 2006, he moved to Monash University as a senior research fellow. He started his independent research career at UNSW as a Lecturer in Oct 2010. He also holds a prestigious Australian Research Fellowship from Australian Research Council. Prof Chuan Zhao is interested in discovering novel electroactive nanomaterials and their implications to electrochemical energy storage and conversion, and biomedicine applications. He is also interested in ionic liquids chemistry and its applications for electrochemical energy systems. His group is exploring these new electrode and electrolyte materials for electrocatalysis and applications such as water splitting, fuel cells, CO2 reduction, lithium-air batteries, and gas sensors.The hundreds of papers were published in the high level publications in recent years, including Nat. Comm., PNAS, J. Am. Chem. Soc., Angew. Chem. Int. Ed., as well as many hot papers and highly cited papers.

报告摘要：The increasing demands for clean energy have triggered tremendous research interests on electrochemical energy conversion and storage systems with minimum environmental impact. Electrolytic water splitting holds the promise for global scale storage of renewable energy, e.g., solar and wind in the form of hydrogen fuel, enabling the continuous usage of these diffusive and intermittent energy sources when used together with fuel cells. Nevertheless, the widespread application of water splitting technology has been severely constrained by the use of precious metal catalysts, such as oxides of ruthenium and iridium for the anodic oxygen evolution reaction (OER), and platinum for the cathodic hydrogen evolution reaction (HER). This presentation concerns our recent progress in developing nanoporous, non-precious metal-based and carbon-based water splitting catalysts, as well as our strategies for enhancing the efficiency of these catalysts to a level comparable to that of precious metal catalysts.
