This book covers synthesis, characterization, and applications of diverse types of nanomaterials. Specifically, it describes carbon, graphene, and graphene oxide-based nanomaterials and their use for environmental remediation; rare-earth ions-activated nanophosphors and their application; lanthanide-based oxides as advanced nanostructured materials for organic decontamination; and advanced functional nanomaterials for pollutant sensing and water remediation. The chapters explore the use of nanomaterials in solid-phase extraction technique, design of colorimetric sensor based on gold...
