The successful in situ synthesis of metallophthalocyanines in mesoporous matrices is presented in this report. To overcome the high hydrophobicity of phthalocyanine (Pc) compounds in conventional wet chemical methods, a simple but effective route is developed to incorporate the metallophthalocyanines into the mesoporous matrix via an in situ reaction process between pre-loaded metal ions and 1,...

Iron-containing materials have been prepared following several strategies of synthesis and using different silica supports (amorphous, zeolitic and mesostructured materials). Activity and stability of these materials was evaluated on the wet peroxide oxidation of phenol under mild reaction conditions (100 degrees C, air pressure of 1MPa and stoichiometric amount of hydrogen peroxide for the com...

The design of nanoparticles desired sizes and shapes 2D nanostructured materials is challenging important due to their unique physical chemical properties. One the most common methods for generation metal wet synthetic route in which ions are reduced formed particles stabilized liquid phase. Here we show a facile powerful method synthesize gold solid agarose gel utilizing diffusion reagents usi...

A 2D porous carbon material with excellent electrochemical performance as an electrode in supercapacitors was synthesised using a Sonogashira–Hagihara cross-coupling/Bergman cyclization cascade reaction.

Two approaches for metal ion incorporation were employed to introduce Ca2+ into SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed by two different methods; calcination and solvent extraction. The obtained catalysts were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX), and FT-IR spectroscopy. The bas...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

Solid electrolytes based on doped cerium oxide, Ce(M)O2-δ (M = rare-earth cations), are of considerable interest for potential use in low temperature solid oxide fuel cells (LTSOFCs) due to its higher ionic conductivity than YSZ based solid electrolyte.  In this research work, crystalline, pure Ce1-xMxO2-δ (where M = Gd or Sm, x = 0.10 or 0.20) based nanoparticles were prepared by chemical prec...

Introduction: Optimization of waste collection systems can reduce waste management costs. In this study, optimization of the waste collection system of district 3 of Yazd municipality of Iran has been investigated using underground containers. Materials and Methods: In this research, after collecting information and performing field inspections, the statistical and raster information obtained ...

ZnTe quantum dots (QDs) have been very attractive because of their potential applications in optoelectronic devices operating in the blue-green region of the spectrum. This paper describes a convenient one-step synthesis of high-quality ZnTe QDs in high-temperature organic solution with high yield. Anhydrous zinc chloride was dissolved in phenyl ether under argon protection and oleic amine was ...

Ammonia was directly synthesised from wet air at 400 °C at atmospheric pressure. A new perovskite Sm(0.6)Ba(0.4)Fe(0.8)Cu(0.2)O(3-δ) was used as the electrocatalyst for electrochemical synthesis of ammonia. Ammonia formation rates of 9.19 × 10(-7) mol s(-1) m(-2) and 1.53 × 10(-6) mol s(-1) m(-2) were obtained at 400 °C when wet air and wet N2 were introduced into a simple single chamber reacto...
