Fabrication of mesoporous SiO2–C–Fe3O4/γ–Fe2O3 and SiO2–C–Fe magnetic composites

Synthesis of colloidal silica nanoparticles of a tunable mesopore size and their application to the adsorption of biomolecules

“…These experiments were performed in a thermogravimetric analyser, in air up to 600°C. Such a high level of adsorption of hemoglobin by far exceeds the amounts reported in the literatures [31][32][33][34][35][36]. This is illustrated in Fig.…”

“…5B compares the normalized hemoglobin adsorption rates on mesoporous silica nanoparticles (MSN-T-1 and MSN) with those of two representative porous materials, i.e. bimodal mesoporous carbon [35] and mesostructured SBA-15 silica [36]. It can be seen that the adsorption of hemoglobin on silica nanoparticles is markedly faster than in the case of the reference materials.…”

Synthesis of confined Ag nanowires within mesoporous silica via double solvent technique and their catalytic properties

“…After incorporating Ag nanowires, the BET surface area of SBA-15 decreases from 994.9 m 2 /g to 444.1 m 2 /g and the cumulative adsorption pore volumes decreases from 1.22 cm 3 /g to 0.68 cm 3 /g. These decreases suggest that Ag has been incorporated into the mesochannels of SBA-15 [32]. …”

Cobalt salophen complex supported on magnetic nanoparticles as an efficient reusable catalyst for oxidation of benzylic alcohols

“…Nowadays, magnetic nanopar ticles (MNPs) have attracted increasing interest as promising alternatives for the immobilization of homogeneous catalysts because of their unique properties including a large surface-to-volume ratio, magnetism, low toxicity, biocompatibility and their potential applications in various fields [15][16][17][18][19][20] . In this study, we wish to present a novel method for the immobilization of a Co (II) salophen complex on imidazole functionalized silica coated cobalt ferrite nanoparticles (Co (salophen)-imid-Si@Si-MNPs).…”
