Photocatalysts in Advanced Oxidation Processes for Wastewater Treatment comprehensively covers a range of topics aiming to promote the implementation of photocatalysis at large scale through provision of facile and green methods for catalysts synthesis and elucidation of pollutants degradation mechanisms. This book is divided into two main parts namely "Synthesis of effective photocatalysts" (Part I) and "Mechanisms of the photocatalytic degradation of various pollutants" (Part II). The first part focuses on the exploration of various strategies to synthesize sustainable and effective photocatalysts. The second part of the book provides an insights into the photocatalytic degradation mechanisms and pathways under ultraviolet and visible light irradiation, as well as the challenges faced by this technology and its future prospects.
Elvis Fosso-Kankeu has a doctorate degree from the University of Johannesburg in South Africa. He is currently a Full Professor in the School of Chemical and Mineral Engineering at the North-West University in South Africa. His research focuses on the prediction of pollutants dispersion from industrial areas, and on the development of effective and sustainable methods for the removal of inorganic and organic pollutants from polluted water. He has published more than 200 journal articles, books, book chapters and conference proceeding papers. Sadanand Pandey is a Research Professor in Yeungnam University, South Korea. He received his PhD degree in polymer chemistry in 2009, India. In the period 2011-2013, he worked in the Materials Research Centre (MRC) of the Indian Institute of Science. His 70+ high impact international publications have received more than 2000 google scholar citations in the past 5 years. He is leading a research project focused on the design of new nanostructured inorganic and hybrid organic-inorganic materials and their application as adsorbents, catalysts and gas sensor. Suprakas Sinha Ray is a chief researcher in polymer nanocomposites at the CSIR, India with a PhD in physical chemistry from the University of Calcutta (2001) and director of the DST-CSIR National Centre for Nanostructured Materials. Ray's current research focuses on polymer-based advanced nanostructured materials and their applications. Prof. Ray is the author of 4 books, co-edited 3 books, 30 book chapters on various aspects of polymer-based nano-structured materials & their applications, and author and co-author of more than 300 articles in high-impact international journals, 30 articles in national and international conference proceedings.
