Metal Fe3+ ions assisted synthesis of highly monodisperse Ag/SiO2 nanohybrids and their antibacterial activity

A novel antifouling and antibacterial surface-functionalized PVDF ultrafiltration membrane via binding Ag/SiO2nanocomposites

“…, the SiO 2 and Ag/SiO 2 nanomaterials exhibit a broad XRD reflection peak around 23°, which could be assigned to the amorphous structures of SiO 2 . The Ag/SiO 2 has diffraction peaks different from those of the SiO 2 , exhibiting diffraction peaks at 38.2°, 44.1°, 64.5°, 77.5° and 81.4°, respectively, corresponding to the (111), (200), (220), (311) and (222) crystalline planes of the face‐centered cubic (fcc) structured Ag (JCPDS, 04‐0783) . This result affirms that Ag nanoparticles are deposited onto the surface of SiO 2 nanoparticles.…”

BN/Ag hybrid nanomaterials with petal-like surfaces as catalysts and antibacterial agents

“…Therefore, it is extremely important to use supports which could not only improve the colloidal stability of Ag NPs but also improve their antibacterial characteristics. A wide range of materials, such as graphene oxide [ 30 – 31 ], carbon nanotubes [ 32 ], SiO 2 [ 33 ], Fe 3 O 4 [ 34 ], ZnO [ 35 ], CuO [ 36 ], TiO 2 [ 37 ] and others, have been tested as the supports for Ag NPs. Compared with the previous studies, our approach possesses the notable advantages owing to the particle spherical shape, their optimal size and petal-like surfaces resulting in larger contact areas.…”

Recyclable SERS substrates based on Fe2O3–Ag hybrid hollow microspheres with crumpled surfaces

“…The high-resolution TEM (HRTEM) images (Fig. 2E and F) reveal well defined fringes with the inter-planar spacing distances of 0.24 and 0.37 nm corresponding to the (111) planes of the cubic phase of Ag 30,31 and the (012) planes of Fe 2 O 3 , 32 respectively.…”
