Anatase/rutile mixed-phase TiO2 nanoparticles were synthesized through a simple sol-gel route with further calcination using inexpensive titanium tetrachloride as source, which effectively reduces the production cost. The structural and optical properties of prepared materials characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis adsorption. specific surface area was also analyzed Brunauer–Emmett–Teller (BET) method. anatase/rutile nanocomposites containing...
The sculpturing effect of chloride ions on the shape transformation silver nanoparticles is presented. UV−vis spectroscopy and transmission electron microscopy (TEM) were used to monitor evolution nanoplates. Cl− can etch corners side faces nanoprism, resulting are disk-like in shape. dissolved atoms would aggregate form small clusters, which stabilized by citrate ions. facet-selective etching mainly attributed surface energy difference each face nanoplate. thickness nanodisk increased...
Successfully using the solution phase, we have prepared, in large quantities, uniform hexagonal silver nanoplates developed from triangular nanoprims by employing a photoinduced technique. The growth process was characterized ultraviolet−visible (UV−vis) spectroscopy, transmission electron microscope (TEM), and high-resolution (HRTEM). UV−vis spectra showed that three bands of appear at 341 (weak), 368 (medium), 498 (strong) nm. TEM images had an average edge size 25.9 nm thickness 15.7 ±...
We present a method for the tunable production of monodisperse silver nanoparticles. Using monochromatic light different laser wavelengths to irradiate an initial solution seed crystals, size and shape products can be controlled. By monitoring absorption spectrum during growth, it is found that initially maximum shifts longer broadens, indicating increase in particle dispersion. Remarkably, this effect comes halt reverses, displaying shift shorter simultaneously narrower bandwidths until, on...
Silver nanocrystals with tetrahedral shapes and {111} faces have been synthesized by the light-driven growth method in an aqueous solution. The of T(d) symmetry were formed under effect tartrate citrate as structural-directing reagents at appropriate stages reaction. Further, may be assembled through electrostatic interaction to develop large-scale particle surfaces sharp vertexes, which can generate strong localized electromagnetic field for surface-enhanced Raman scattering (SERS) studies....
A large quantity of well-defined silver nanodisks was prepared by heating nanoprisms in aqueous solution. By adjusting only the time, conversion morphology and size nanoplates could be easily effectively controlled. The local surface plasmon resonance (LSPR) tuned a certain range heat-aging process. gradual blue shift their LSPR bands with aging time observed from 655 to 472 nm. transformation during heat captured transmission electron microscopy (TEM). TEM images indicate that atoms on...
A new method for the preparation of mesoporous TiO2 with a surface deposited nanoparticles Ag and AgBr was developed. Cetyltrimethylammonium bromide (CTAB) used as both template agent bromine source in process TiO2. Mesoporous containing CTAB synthesized by sol–gel method, dipped into AgNO3 solution to form AgBr/TiO2 nanocomposite. The nanocomposite irradiated visible light accelerate photolysis AgBr, forming Ag/AgBr/TiO2 photocatalyst. photocatalyst characterized small angle X-ray...
A series of shapes silver nanoplates were achieved by adjusting the concentration citrate in colloid photoinduced process. The local surface plasmon resonance (LSPR) could be tuned gradually a range from 740 to 440 nm. In contrast, LSPR band can photomediated again long wavelength region within 620−690 nm only adding more colloidal system. initial nanoprisms converted discal shape under light effect. this conversion, coupling effect and source speeds up photothermal reaction. Subsequently,...
Time-resolved extinction spectroscopy is employed to study the reaction kinetics in shape-conversion involving halide ions (including Cl−, Br− and I−) etching (sculpturing) silver nanoplates. A series of time-resolved spectra are obtained during situetching process evolution surface plasmon resonance (SPR) nanoparticles analyzed. Spectral analysis indicates that conversion nanoprisms starts simultaneously with emergence nanodisks when added. The rate different evaluated through in-plane...

Abstract The leakage of iodine and its radioactive isotopes poses a major threat to ecosystems human health, emphasizing the need for effective recyclable capture materials. Covalent organic frameworks (COFs), characterized by high surface areas, tunable pore sizes, excellent chemical stability, are ideal candidates adsorption applications.
