ZnO/bentonite Nanocomposites Prepared with Solid-state Ion Exchange as Photocatalysts

A Comparative Study of Photocatalytic Activity of ZnO/activated Carbon Nanocomposites Prepared by Solid-state and Conventional Precipitation Methods

ZnO/activated carbon nanocomposites (ZnO/ACns) were synthesized by applying two different solid-state and precipitation methods. Precipitation method was initiated with zinc chloride and sodium hydroxide as starting materials in the presence of activated carbon. The synthesized sample was calcined at 250 °C for 1 h. The preparation of nanocomposite by solid-state method was accomplished by heat...

Chemically bonded graphene/BiOCl nanocomposites as high-performance photocatalysts.

After the successful solvothermal synthesis of graphene (GR) from ethanol and sodium, we obtained chemically bonded graphene/BiOCl (GR/BiOCl) nanocomposite photocatalysts via a facile chemical-bath method. A significant enhancement was observed in the photodegradation of methylbenzene, which was largely ascribed to the chemical coupling effects between Bi and C, as shown by X-ray photoelectron ...

Ion-beam Mixing and Solid-state Reaction

Vapor-deposited Zr-Fe multilayered thin films with various wavelengths and of overall composition either 50% Fe or Fe-rich up to 57 % Fe were either irradiated with 300 keV Kr ions at temperatures from 25K to 623 K to fluences up to 2 x 10l6 cm-2, or simply annealed at 773K in-situ in the Intermediate Voltage Electron Microscope at Argonne National Laboratory. Under irradiation, the final react...

Solid State Porphyrin Based Mercury Ion Sensors

Among the heavy metals, mercury is often considered the most toxic; moreover, current methods used to sense and quantitate mercury in the environment are expensive and labor intensive. In response, the sensor community has sought new approaches to detect and quantitate mercury. One such approach is the use of porphyrins as selective reagents for the detection of mercury. Porphyrins have shown g...

Mechanochemical Synthesis of TiO2 Nanocomposites as Photocatalysts for Benzyl Alcohol Photo-Oxidation

TiO₂ (anatase phase) has excellent photocatalytic performance and different methods have been reported to overcome its main limitation of high band gap energy. In this work, TiO₂-magnetically-separable nanocomposites (MAGSNC) photocatalysts with different TiO₂ loading were synthesized using a simple one-pot mechanochemical method. Photocatalysts were characterized by a number of techniques and ...
