This book focuses on the electrochemical and nanostructural properties of new photoanode/electrolyte combinations used in the development of novel surface-modified nanomaterials for environmental applications. As water treatment is rapidly becoming a global challenge due to the increasing complexity and number of the various pollutants present, the book explores fundamental issues relating to environmental applications of nanomaterials. It addresses relevant topics ranging from electrochemical synthesis and characterization, to applications of photoanodes in corrosion prevention and biosensors for wastewater treatment. Featuring up-to-date experimental results on nanomaterials for detection of pharmaceuticals and heavy metals in wastewater, this contributed volume is useful to electrochemical researchers, materials scientists, and chemical and civil engineers interested in advanced photoelectrochemical research for environmental applications.

Autorentext

Dr. Onoyivwe Monday Ama received a Ph.D. degree in chemistry at the University of Johannesburg, South Africa, in 2017. He is the author of twenty-one international articles in high-impact international journals. His multi-disciplinary work cuts across electrochemistry, water science, materials science, and nanotechnology. It successfully highlights the applicability of exfoliated graphite nanocomposites in electrochemical technology. His contribution paves the way for the development of electrochemical reactors, powered by solar light in our society, for water treatment shortly. He is a visiting research associate in the Centre for Nanostructures and Advanced Materials, DSI-CSIR Nanotechnology Innovation Centre, and Council for Scientific and Industrial Research, Pretoria, South Africa. He is the author of 1 book and 12 book-chapters on several aspects of electrochemistry and author and co-author of 21 articles in high-impact international journals.
