Abstract: Water is a fundamental component within the Water-Energy-Food Nexus, crucial for fostering sustainability. Modern environmental engineering faces substantial grand challenges, including pollution mitigation, climate change adaptation, and ensuring sustainable food, water, and energy supplies. This presentation will address two main areas: firstly, the development of efficient chemical treatment technologies for combating contamination by per- and polyfluoroalkyl substances (PFAS); and secondly, the exploration of multidisciplinary approaches to advance novel technologies and materials vital for environmental sustainability and energy applications. The first segment focuses on addressing PFAS, a widespread class of organofluorine compounds with severe implications for both human health and the environment. Utilizing the UV/sulfite photochemical system – an emerging advanced reduction process (ARP) – demonstrates the efficacy of hydrated electrons (eaq–) in chemically destroying a broad spectrum of PFAS compounds. Investigating critical structure–reactivity relationships elucidates distinct reaction pathways, particularly under basic conditions. Through system optimization and subsequent oxidation (via heat-activated persulfate), transformation products undergo complete mineralization, thus closing the fluorine mass balance. The second segment delves into pioneering ARPs, materials designed for pollution management and resource recovery, and electrochemical carbon dioxide reduction, all of which contribute to the holistic framework of the Water-Energy-Food Nexus. These integrated research endeavors aim to yield tangible societal benefits by offering innovative strategies to combat environmental challenges, optimize resource utilization, and bolster energy storage capabilities.
