**About the Editors**

**Olivier Monfort** is an expert in photochemical processes for the treatment of water from organic contamination using nanomaterials. He received his PhD in Inorganic Chemistry in 2017 at the Faculty of Natural Sciences, Comenius University in Bratislava (FNS CU), Slovakia. He was a postdoctoral fellow in France at the Ecole National Superieure de Chimie de Rennes (from 2017 to ´ 2018) and at the Universite Clermont Auvergne (from 2018 to 2019). At the end of 2019, he returned ´ to his alma mater at Comenius University as a senior scientist, where he is now the co-leader of the Laboratory of Photoactive Materials at the Department of Inorganic Chemistry, FNS CU. In 2021, he was the finalist of the prestigious "Falling Walls Lab Slovakia". To date, Dr. Olivier Monfort has an h-index of 10, published 2 book chapters, and received several financial supports for mobility and scientific projects.

**Yanlin Wu** is an expert in iron chemistry and radicals-based oxidation systems for the degradation of contaminants of emerging concern in water and soil. She received her PhD degree in 2014 from a "co-tutelle" between Fudan University, China and Universite Clermont Auvergne, ´ France. She started her scientific career as postdoctoral fellow at the Universite Clermont Auvergne ´ (from 2014 to 2015) and then at the Tongji University (from 2015 to 2017). Since 2017, Dr. Yanlin Wu has been employed as associate researcher at Fudan University, China. In her short career, she has received the financial support from the China Postdoctoral Science Foundation (2016), National Natural Science Foundation of China (2017) and Foundation of Key Laboratory of Yangtze River Water Environment, Ministry of Education (2021). She has published more than 30 research papers.
