“…In particular, its interlayer space has been used for the synthesis of material and biomaterial NPs as the support for anchoring transition metal complex catalysts and as adsorbents for cationic ions. 30,31 In addition, various production methods have been described for the synthesis of Ag-NP colloids using silver salt as the initial materials; for instance, chemical reduction, [32][33][34][35] aerosol spraying technique, 36 reverse micelle, 37 lamellar liquid crystal, 38 microemulsion, 39 micelle, 40 capping agent method, 41 and photochemical reduction (ie, microwave, 42 electron beam, 43 ultraviolet (UV)-irradiation, 44,45 and γ-irradiation). [46][47][48] Of these techniques, the use of γ-irradiation in the preparation of Ag-NPs has been demonstrated to have a number of highly advantageous properties compared with conventional chemical and photochemical methods, namely:…”
