澳大利亞阿德萊德大學(The University of Adelaide)鄭堯教授、焦研教授來我校進行學術交流并作學術報告

應蘇州科技大學數理學院/材料科學與器件研究院邀請,澳大利亞阿德萊德大學(The University of Adelaide)鄭堯教授、焦研教授來我校進行學術交流并作學術報告,歡迎廣大師生參加!

   一:

  報 人:鄭堯  教授

  報告題目:Design of highly efficient electrocatalysts: from fundamental to practical

  報告時間:20181228日(星期五)下午1:30

  報告地點:石湖校區化生學院(逸夫樓B棟)1139會議室

報告人簡介:鄭堯教授,2014年于澳大利亞昆士蘭大學獲得化學工程博士學位,目前為澳大利亞科學院DECRA研究員,作為項目負責人已獲澳大利亞政府資助100余萬澳元。主要研究方向為新型納米材料的制備及其在能源轉換中的應用,包括氫析出反應,二氧化碳、氮氣還原反應等。著重采用理論計算與實驗相結合的手段進行高性能催化劑的設計與開發。已在Nature Energy, Nature Commun., J. Am. Chem. Soc., Angew. Chem. Int. Ed., Chem. Soc. Rev.等國際權威期刊雜志上發表論文76篇日博体育平台注册,被引用10000余次。

報告簡介: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.

  報告題目:Design of Carbon-Based Electrocatalysts for Clean Energy Conversions – A Theoretical Point of View

  報告時間:20181228日(星期五)下午2:15

  報告地點:石湖校區化生學院(逸夫樓B棟)1139會議室

報告人簡介:焦研教授,2012年獲得澳大利亞昆士蘭大學化學工程博士學位,目前在澳大利亞阿德萊德大學擔任Vice Chancellor‘s Fellow。研究方向為使用密度泛函理論(DFT)設計高效清潔能源轉換新型催化劑,已在Nature Energy, Nature Commun., J. Am. Chem. Soc., Angew. Chem. Int. Ed.等雜志上發表了45篇學術論文,被引用9000余次。

報告簡介: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.
