Polyoxometalate-Based Materials and Applications focuses on recent progress in polyoxometalate-based materials for various electrochemical and biomedical applications. First, the structure, composition, classification, and properties of POMs-based materials are introduced. Then, their design for energy applications such as supercapacitors, batteries, hydrogen production are discussed. Finally, their use in biomedical (antibacterial, antiviral, cancer prevention/treatment) and sensing applications are reviewed. This book will be a great resource for materials scientists, engineers, chemists, and chemical engineers.
