Minghua Zhou obtained his Ph.D. from Zhejiang University (China) in 2003, and then served there as an assistant and an associate professor from 2003 to 2006. After his postdoctoral research at the University of Sydney for two years, he was recruited as a full Professor by Nankai University in 2008. His research interests include water and wastewater treatment, environmental catalysis and materials, microbial fuel cells and advanced oxidation processes, particularly Electrochemical Advanced Oxidation Processes including electro-Fenton. He has published more than 150 scientific articles, 2 books and 3 book chapters. He is a member of the Editorial Board of several scientific journals, such as Separation Purification Technology. Mehmet A. Oturan is currently Professor of Exceptional Class at the University Paris-Est and Head of the Environmental Chemistry group. His current research interests include advanced oxidation processes and particularly electrochemical advanced oxidation processes including electro-Fenton process of which he invented the “carbon-felt cathode” version and their application to wastewater treatment and soil remediation. He has supervised 41 PhD, published more than 180 scientific articles, 2 books and 8 book chapters and delivered more than 50 invited talks at national/international scientific congresses and at various institutions. His current h-index is 51 with total citation more than 8000 (Web of Science). He serves now as the Associate Editor of Environmental Chemistry Letters and Sustainable Environmental Research. Ignasi Sirés obtained his Ph.D. in Chemistry from the Universitat de Barcelona (UB, Spain) in 2007. He also became a Materials Engineer (UB and the Universitat Politècnica de Catalunya). He was awarded the “Oronzio and Niccolò De Nora Foundation Prize in Environmental Electrochemistry” in 2010 (ISE), the “CIDETEC 2011 Prize for Young Researchers in Electrochemistry” (Spain) and the prestigious “Carl Wagner Medal of Excellence in Electrochemical Engineering 2014” (WPEE, EFCE). In 2014 he became Tenured Assistant Professor at the UB. He is interested in all aspects of environmental electrochemistry for wastewater treatment, including new electrode materials, the study of reaction intermediates, process scale-up, the study of coupled cathodic/anodic processes and coupling with solar energy. His major efforts focus on Fenton’s reaction chemistry.
