Preface

With the increasing awareness of the global sustainability challenges, how to accomplish environmental conservation and energy production without the depletion of natural sources has attracted great attention. Through fabricating materials at the nanometer scale, nanotechnology has facilitated an efficient and economically and environmentally acceptable solution for waste treatment and energy production. This book is devoted to illustrating the subject of sustainable nanotechnology being used to promote more efficient environmental sustainability, including environmental remediation and energy optimization. First, a comprehensive discussion of the latest advances in using green nanotechnology to address the global challenges in water purification, CO₂ management, plastic waste remediation, food waste valorization, toxic chemical pollution, and energy efficiency will be provided, followed by new opportunities that green nanotechnology has created in the production of alternative renewable energy under the premise of low natural resource consumption and minuscule toxicity production. The perspectives and future research directions of green nanotechnology to achieve more environmental sustainability will also be presented in the proposed chapters. This book offers an important reference for the research community to understand more about green nanotechnology and its application in sustainable development and circular economy, as well as the perspectives for future R&D directions.
