Abstract

To obtain a recyclable surface-enhanced Raman scattering (SERS) material, we developed a composite of Fe{sub 3}O{sub 4}/SiO{sub 2}/Ag with core/shell/particles structure. The designed particles were synthesized via an ultrasonic route. The Raman scattering signal of Fe{sub 3}O{sub 4} could be shielded by increasing the thickness of the SiO{sub 2} layer to 60 nm. Dye rhodamine B (RB) was chosen as probe molecule to test the SERS effect of the synthesized Fe{sub 3}O{sub 4}/SiO{sub 2}/Ag particles. On the synthesized Fe{sub 3}O{sub 4}/SiO{sub 2}/Ag particles, the characteristic Raman bands of RB could be observed when the RB solution was diluted to 5 ppm (1x10{sup -5} M). Furthermore, the synthesized particles could keep their efficiency till four cycles. -- Graphical Abstract: Fe{sub 3}O{sub 4}/SiO{sub 2}/Ag particles, a recyclable surface-enhanced Raman scattering (SERS) material, were designed and synthesized via a simple ultrasonic route.

Magnetically separable {gamma}-Fe{sub 2}O{sub 3}-SiO{sub 2}-Ce-doped TiO{sub 2} core-shell nanocomposites: Fabrication and visible-light-driven photocatalytic activity

Journal Article He, Minqiang; Li, Di; Jiang, Deli; ... - Journal of Solid State Chemistry

Novel visible-light-induced {gamma}-Fe{sub 2}O{sub 3}-SiO{sub 2}-Ce-doped-TiO{sub 2} core-shell nanocomposite photocatalysts capable of magnetic separation have been synthesized by a facile sol-gel and after-annealing process. The as-obtained core-shell nanocomposite is composed of a central {gamma}-Fe{sub 2}O{sub 3} core with a strong response to external fields, an interlayer of SiO{sub 2}, and an outer layer of Ce-doped TiO{sub 2} nanocrystals. UV-vis spectra analysis indicates that Ce doping in the compound results in a red-shift of the absorption edge, thus offering increased visible light absorption. We show that such a {gamma}-Fe{sub 2}O{sub 3}-SiO{sub 2}-Ce-doped-TiO{sub 2} core-shell nanocomposite with appreciated Ce doping amount exhibitsmore »« less

Rapid Detection of Tetrodotoxin Using Surface-Enhanced Raman Spectroscopy and Fe{sub 3}O{sub 4}/SiO{sub 2}/Au Gold/Magnetic Nanoparticles

Journal Article Neng, Jing; Wang, Xujun; Jia, Kan; ... - Journal of Applied Spectroscopy

Fe{sub 3}O{sub 4} nanoparticles were first modified with tetraethoxylsilane to form Fe{sub 3}O{sub 4}/SiO{sub 2} nanoparticles, followed by the addition of 3-aminopropyltriethoxysilane and 3-thiolpropyltriethoxysilane to introduce –NH{sub 2} and –SH groups to the surface of Fe{sub 3}O{sub 4}/SiO{sub 2} nanoparticles. Gold nanoparticles were further assembled on the surface of Fe{sub 3}O{sub 4}/SiO{sub 2} via the electrostatic adsorption of –NH{sub 2} and the Au–S bond to produce stable core–shell Fe{sub 3}O{sub 4}/SiO{sub 2}/Au gold/magnetic nanoparticles. These Fe{sub 3}O{sub 4}/SiO{sub 2}/Au gold/magnetic nanoparticles were characterized by a variety of techniques such as transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX),more »« less

Journal Article Wang, Jian; Fan, Xi’an; Wu, Zhaoyang; ... - Journal of Solid State Chemistry

Fe{sub 3}Si{sub 0.7}Al{sub 0.3}@SiO{sub 2} core–shell particles and Fe{sub 3}Si/Al{sub 2}O{sub 3} soft magnetic composite core have been synthesized via a modified stöber method combined with following high temperature sintering process. Most of conductive Fe{sub 3}Si{sub 0.7}Al{sub 0.3} particles could be uniformly coated by insulating SiO{sub 2} using the modified stöber method. The Fe{sub 3}Si{sub 0.7}Al{sub 0.3}@SiO{sub 2} core–shell particles exhibited good soft magnetic properties with low coercivity and high saturation magnetization. The reaction 4Al+3SiO{sub 2}=2α-Al{sub 2}O{sub 3}+3Si took place during the sintering process. As a result the new Fe{sub 3}Si/Al{sub 2}O{sub 3} composite was formed.

Trace Chemical Detection Using Intercalated MXenes as a Signal Enhancing Substrate in Optical Probes

Conference Allen-Perry, Kemryn; Autrey, Daniel; Lascola, Robert

MXenes are 2D materials composed of layered transition metal nitrides or carbides. These materials are synthesized by HF exfoliation from MAX phases (Ti{sub 3}AlC{sub 2}). The 2D nanomaterial was synthesized by the removal of the 'A' element, resulting in a Mxene product (Ti{sub 3}C{sub 2}). MXenes have the general formula M{sub n+1}X{sub n}T{sub x}, where M is an early transition metal, X is Carbon and/or Nitrogen, and T accounts for surface terminated functional groups such as Fluoride, hydroxyl, and oxygen. These materials have very unique properties, similar to graphene, that allows them to be applied in a variety of tracemore »« less
