Characteristics of the materials: A) The preparation of G3 or G1 glass and B) supported nanoparticles (Ag or CuO) on kaolin. C) XRD patterns of G1 and G3 glasses, and D) kaolin (K), supported silver nanoparticles on kaolin (K-nAg), and supported copper oxide nanoparticles on kaolin (K-nCu). Peaks ascribed to metallic silver and to copper oxide are identified with an asterisk.
