Per- and poly-fluoroalkyl substances (PFAS) are emerging anthropogenic chemicals that have been widely used in clothing and coating industry. However, PFAS cause serious issues to human health such as cancer, disruptions of immune systems, reproductive problems etc. Current PFAS treatment technologies have many limitations such as secondary pollution resulted from PFAS- condensed wastes and used material, and high energy and economic costs.This project will rationally design high-performance Al2O3 supported Mn (Mn/Al2O3) catalysts for PFAS degradation in aqueous environments via precise control of the wettability of catalysts and study of the reaction mechanism using advanced ex/in-situ characterization techniques.The proposed research is interdisciplinary that lays at the interface of chemistry and materials science. The knowledge generated in this fellowship will greatly benefit multiple research areas e.g. catalyst design, wettability, surface science and water remediation. The technology developed in this fellowship will significantly improve the quality of life by establishing an innovative method for water purification with minimized environmental impact.This project will be delivered by the fellow, Dr. Xiaoxi Guo, with a strong expertise in water remediation particularly using advanced oxidation process (AOP), under the supervision of Dr. Yao Lu who has a strong track-record in wetting and surface science, and the mentorship of Prof. Marina Resmini that has extensive experience in coordinating EU projects and mentoring early career researchers.This fellowship will provide new expertise and training to the fellow on: 1) advanced synchrotron radiation techniques, including the use of Diamond Light Source facilities; 2) surface wettability control; 3) professional development for academics. The fellow will bring her knowledge of water treatment that will complement the project and enhance the current expertise of the host.

全氟烷基物质和多氟烷基物质(PFAS)是一种新兴的人为化学品，已广泛应用于服装和涂料工业。针对目前PFAS处理技术存在的诸多局限性，如PFAS的浓缩废物和废旧材料造成的二次污染，以及较高的能源和经济成本，本课题将通过精确控制催化剂的润湿性和利用先进的外/原位表征技术研究反应机理，合理设计高性能的Al_2O_3负载的Mn(Mn/Al_2O_3)催化剂，用于水环境中PFAS的降解。该奖学金所产生的知识将极大地惠及多个研究领域，如催化剂设计、润湿性、表面科学和水修复。通过建立一种对环境影响最小的水净化创新方法，该奖学金开发的技术将显著提高生活质量。该项目将由郭小溪研究员完成，他在水修复方面拥有丰富的专业知识，特别是使用高级氧化工艺(AOP)，并在润湿和表面科学方面拥有丰富记录的姚路博士的指导下，以及在协调欧盟项目和指导早期职业研究人员方面拥有丰富经验的Marina Resmini教授的指导下进行。该奖学金将为该研究员提供新的专业知识和培训：1)先进的同步辐射技术，包括使用钻石光源设施；2)表面润湿性控制；3)学术专业发展。这位研究员将带来她在水处理方面的知识，这将补充该项目并增强东道主目前的专业知识。
