This book covers the various aspects of nanohybrid materials and its composites for their application in treatment of toxic textiles dyes for cleaning the environment especially water and wastewater. The book first looks into the various preparation and characterization techniques for nanohybrid materials. The replacement of other conventional materials with highly efficient (high surface area, pore size, and chemical and mechanical strength) nanohybrid materials and their application in the field of environmental purification through treatment of textile dyes is highlighted in the later part of the book. The book caters to students, researchers, and scientists who are working in the field of wastewater treatment for incorporating novel materials to remove toxic textile dyes from contaminated wastewater.
