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

报告人:郑尧  教授

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.
