下午2点直播| 乔世璋教授：面向可持续燃料和化学品生产的电催化炼制研究

In recent years, Chinese and Australian researchers have maintained close and extensive cooperation in the fields of material science, physics, chemistry, biology and the others. The close international cooperation between the two sides has yielded a large number of important research results and actively promoted the development of relevant scientific fields.

China-Australia Quantum Science and Advanced Materials Series of Lectures are sponsored by China-Australia Scholars Federation and held by Sui Tong Science Cloud. This cutting-edge academic communication aims at promoting academic exchanges and cooperation between China and Australia in quantum science, advanced materials and other related fields.

These series of lectures, as an great opportunity, will provide a platform for further communication between domestic and foreign researchers. we will invite many renowned Chinese and Australian scholars and researchers to share the latest research results, disseminate scientific knowledge and discuss the research direction.

Dr Shizhang Qiao is the founding Director of Centre for Materials in Energy and Catalysis and a Chair Professor at the School of Chemical Engineering and Advanced Materials of the University of Adelaide (UoA).

His research expertise is in nanomaterials for new energy technologies (electrocatalysis, photocatalysis, batteries).

He has also been awarded an ARC ARF Fellowship and an ARC APD Fellowship. He is an Associate Editor of Journal of Materials Chemistry A, a Fellow of Institution of Chemical Engineers (FIChemE), Royal Society of Chemistry (FRSC) and Royal Australian Chemical Institute (FRACI). Dr Qiao is a Thomson Reuters/Clarivate Analytics Highly Cited Researcher in two categories of Chemistry and Materials Science.

Electrocatalytic process is an attractive route to enable the transition of fuel and chemical production from fossil fuels to renewables. Specifically, powered by renewable electricity (e.g., solar, wind and hydro power), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) can efficiently split water into green hydrogen, CO₂ reduction reaction (CRR) can convert CO₂ emissions to transportable fuels and commodity chemicals, and N₂ reduction reaction (NRR) can potentially manufacture fertilizers at ambient conditions.[1,2] A crucial step in realizing this prospect is the knowledge-guided design of optimal electrocatalysts with high activity and selectivity for anticipated reaction pathways.

In this presentation, I will talk about our recent progress in mechanism understanding and material innovation for a series of crucial electrocatalytic reactions (OER, HER, CRR, NRR, ORR, etc.), which are achieved by combining atomic-level material engineering, electrochemical evaluation, theoretical computations, and advanced in-situ characterizations.[3-10] A special emphasis is placed on the rational exploration of novel two-dimensional materials and single-atom catalysts.

Keywords : electrocatalysis, atomic-level material engineering, theoretical computations, in situ characterization, single-atom catalysts.
