The book covers the chemistry of various nanosponges, as well as the methods for synthesizing them and altering them chemically, as well as their characterization and uses in environmental remediation. Sensors, adaptable materials for oil clean-up in the sea, the removal of dangerous organic and inorganic pollutants from wastewater, the adsorption of various poisonous and greenhouse gases from the air, and more are just a few of the environmental uses for nanosponges. This book aims to provide broad coverage of recent research progress or up-to-date knowledge addressing various aspects in this field. With this book, we aim to provide the readers with the opportunity to learn about different facets of environmental remediation using nanosponges. Thus, this book scrutinizes the state-of-the-art research and discovery in the use of nanosponges in environmental applications, highlighting the scope to which these novel materials have been incorporated by the community. Beyond bestowing asummary of recent research by major groups in the field, the book presents the approaches behind recent developments, providing a long-lasting situation for experienced researchers and novices in the field. This book also emphasizes the challenges with previous signs of progress and way for further research, details relating to the current pioneering technology, and future perspectives with a multidisciplinary approach. Furthermore, it presents up-to-date information on the economics, toxicity, and regulations related to these novel materials. This book is of interest to those in environmental science and applications, particularly graduate students, young faculty, and others exploring nanosponges.
