Silver nanoparticle-containing submicron-in-size mesoporous silica-based systems for iodine entrapment and immobilization from gas phase

Porous sorbents for the capture of radioactive iodine compounds: a review

“…Few studies have focused on these materials for iodine capture applications. 81,84,86 Mainly, the works by Mnasri et al on silverdoped MCM-41 mesoporous silica, 84 Yang et al on bismuthdoped SBA-15 86 and Chebbi on silver-doped SBA-15 81 can be found in the literature.…”

“…for a better understanding of iodine capture and its performance. [74][75][76][77][78][79][80][81] In addition, new porous sorbents have been added to the list of potential sorbents for iodine trapping, including titanosilicates, 82,83 mesoporous silicas, 6,81,[84][85][86] silverimpregnated silica and alumina (Ag/SiO 2 and Ag/Al 2 O 3 , respectively), 19,35,52,61,65,70,[87][88][89][90][91][92][93][94][95][96][97] silver-functionalized aerogels, chalcogels, 7,98-108 macroreticular ion exchange resins, 16,39,41,42,[44][45][46]50,53,55 metal-and covalent-organic frameworks (MOFs and COFs, respectively) 6,14, and porous organic polymers (POPs).

Facile and Direct Preparation of Ultrastable Mesoporous Silica with Silver Nanoclusters: High Surface Area

“…The four diffraction planes of the crystalline Ag particles are indicated by arrows and are consistent with those reported previously. [14,15,20,35] These low-intensity silver nanoparticle peaks are indicative of very small particle sizes, as also confirmed by TEM (Figure 4(c) and (d)), while the metallic nature of Ag was confirmed by X-ray photoelectron spectroscopy (XPS) (vide infra). Hence, we were unable to apply the Scherrer equation to calculate the Agparticle size.…”

129Xenon NMR: Review of recent insights into porous materials

“…It has been also confirmed to be a powerful tool to obtain fast and reliable information concerning the distribution of metal particles inside the porosity [135] or the internal structure of organically-modified mesoporous materials [136]. and interconnections between main channels.…”
