This book presents the latest research on the synthesis and properties of a regenerative product—nanocrystalline potassium superoxide—embedded in a highly porous glass fiber matrix. It discusses the current state of the art and challenges in developing regenerative materials based on potassium and sodium superoxides, including methods for producing these superoxides and their formulations for regenerative applications. Designed for scientists, engineers, postgraduate students, and undergraduates specializing in the development, design, and operation of sorption technology devices, the book also covers the creation of adsorbents, regenerative products, and filtration materials. It will be of interest to a broad range of professionals involved in chemical protection solutions for both individual and collective safety.
