WetCat-PFAS: Surface wettability on heterogeneous advanced oxidation catalysis for PFAS degradation

全氟烷基和多氟烷基物质（PFAS）是一种新兴的人为化学物质，已广泛应用于服装和涂料行业。然而，PFAS对人类健康造成严重的问题，如癌症，免疫系统的破坏，生殖问题等。目前的PFAS处理技术有许多局限性，如PFAS产生的二次污染-浓缩废物和使用过的材料，本项目将合理设计高性能Al 2 O3负载Mn（Mn/Al 2 O3）催化剂通过精确控制催化剂的润湿性和使用先进的ex/in-原位表征技术。拟议的研究是跨学科的，在化学和材料科学的接口奠定。在这个奖学金产生的知识将大大有利于多个研究领域，如催化剂设计，润湿性，表面科学和水修复。该项目将由郭晓喜博士主持，郭晓喜博士在高级氧化工艺（AOP）水处理方面具有丰富的专业知识，姚璐博士在润湿和表面科学方面有着丰富的经验，他将在他的指导下，通过建立一种创新的水净化方法，大大改善生活质量，并将对环境的影响降到最低。Marina Resmini教授在协调欧盟项目和指导早期职业研究人员方面拥有丰富的经验。该奖学金将为研究员提供以下方面的新专业知识和培训：1）先进的同步辐射技术，包括使用钻石光源设备; 2）表面润湿性控制; 3）学术人员的专业发展。该研究员将带来她的水处理知识，这将补充该项目，并提高东道国目前的专业知识。

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.
