应苏州科技大学数理学院/材料科学与器件研究院邀请,澳大利亚阿德莱德大学(The University of Adelaide)郑尧教授、焦研教授来我校进行学术交流并作学术报告,欢迎广大师生参加!

   一:

  报 人:郑尧  教授

  报告题目:Design of highly efficient electrocatalysts: from fundamental to practical

  报告时间:20181228日(星期五)下午1:30

  报告地点:石湖校区化生学院(逸夫楼B栋)1139会议室

报告人简介:郑尧教授,2014年于澳大利亚昆士兰大学获得化学工程博士学位,目前为澳大利亚科学院DECRA研究员,作为项目负责人已获澳大利亚政府资助100余万澳元。主要研究方向为新型纳米材料的制备及其在能源转换中的应用,包括氢析出反应,二氧化碳、氮气还原反应等。着重采用理论计算与实验相结合的手段进行高性能催化剂的设计与开发。已在Nature Energy, Nature Commun., J. Am. Chem. Soc., Angew. Chem. Int. Ed., Chem. Soc. Rev.等国际权威期刊杂志上发表论文76篇,被引用10000余次。

报告简介:In the past eight years, working with Prof. Shizhang Qiao, we developed different carbon-based (e.g. heteroatoms doped graphene and carbon nitride) nanomaterials for efficient electrocatalysis like oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). The nature of these electrochemical processes and reactivity origin of corresponding electrocatalysts were revealed by a combination approach of atomic imaging, spectrum characterization, electrochemical measurements, and DFT computation. As a result, we established ORR and HER activity trends for carbon-based materials by linking their apparent activities with their intrinsic adsorption energies and electronic structures. We will also discuss some outlooks on the operando experiments together with operando computation on designing electrocatalysts for selective CO2 reduction to hydrocarbon and oxygenates.

  报告题目:Design of Carbon-Based Electrocatalysts for Clean Energy Conversions – A Theoretical Point of View

  报告时间:20181228日(星期五)下午2:15

  报告地点:石湖校区化生学院(逸夫楼B栋)1139会议室

报告人简介:焦研教授,2012年获得澳大利亚昆士兰大学化学工程博士学位,目前在澳大利亚阿德莱德大学担任Vice Chancellor‘s Fellow。研究方向为使用密度泛函理论(DFT)设计高效清洁能源转换新型催化剂,已在Nature Energy, Nature Commun., J. Am. Chem. Soc., Angew. Chem. Int. Ed.等杂志上发表了45篇学术论文,被引用9000余次。

报告简介:Effective candidates for reactions of hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and CO2 reduction reaction (CRR) are often based on metals, while the potential of carbon-based electrocatalysts for these reactions is not fully discovered. In this regard, working with Prof. Shizhang Qiao, we have designed a series of carbon-based electrocatalysts for HER, ORR, OER and CRR by DFT calculations. These carbon-based materials include heteroatoms doped graphene, g-C3N4, and their complexes. In these materials, reaction mechanisms from our theoretical computations are shown to be in good agreement with experimental observations. We successfully established the relationship between the apparent electrochemical performance and the intrinsic surface adsorption behaviour for carbon-based materials. Furthermore, we explored their reactivity origin to guide the design of more efficient electrocatalysts. Finally, we have summarized methods on three levels to improve carbon-based materials’ performance for these reactions.
