Abstract. SAPO-34 and ZnAPO-34 materials (Zn incorporated by isomorphic substitution in AlPO-34 material) were synthesized hydrothermal synthesis using triethylamine (TEA) as the structure directing agent (SDA). The presented both is to chabazite zeolite (CHA). However, they have different properties such textural (Z34 S34 a surface area of ​​485 603 m2/g, respectively), crystal sizes acid prop...

A novel magnetically recoverable and recyclable nanocatalyst, Cu 2 O-Fe 3 O 4 @TNT, has been developed for the synthesis of 1,4-disubstituted 1,2,3-triazoles at room temperature in aqueous medium.

In recent decades, manufacturers’ intense competitiveness to suit consumer expectations has compelled them abandon the conventional workflow in favour of a more flexible one. This new trend increased importance master production schedule and make-to-order (MTO) strategy concepts. The former improves overall planning controls complexity. latter enables businesses reinforce their flexibility prod...

Aqueous Mizoroki-Heck coupling reactions under microwave irradiation (MW) were carried out with a colloidal Pd nanocatalyst stabilized with poly(N-vinylpyrrolidone) (PVP). Many stilbenes and novel heterostilbenes were achieved in good to excellent yields starting from aryl bromides and different olefins. The reaction was carried out in a short reaction time and with low catalyst loading, leadin...

Hydrotalcite nanoparticles were synthesized by co-precipitation of aqueous Mg(NO(3))(2)·6H(2)O and Al(NO(3))(3)·9H(2)O in the presence of urea and subsequent microwave-hydrothermal treatment. The nanoparticles were activated with saturated aqueous Ca(OH)(2), and used to hydrolyze cellulose. A maximum hydrolysis yield of 47.4% with high glucose selectivity (85.8%) was achieved at 423 K. The nano...

Dye sewage is dangerous problem in our environmental aquatics that cause generation of harmful effects for living organism. In this work, because of simplicity, easy operation, high efficiency and no creating secondary pollutants, ultra sound radiation applied for degradation of a synthetic dye, methyl orange using zinc sulfide nano particles decorated on carbon nanotubes as nanocatalyst. ZnS/C...

Research posted today on ES&T’s Research ASAP website (10.1021/es0509836) describes how, in one elegant step, selected bacteria can recover precious metals from industrial waste solutions and deposit them as nanocrystal catalysts on their cell surfaces. By using the metal-covered biomass to clean up toxic chromium wastes, the researchers demonstrated the approach’s potential as a sustainable te...

A bulky organocobalt sandwich-supported Rh nanoparticle is an efficient, stable and recyclable nanocatalyst for hydrolysis of both ammonia borane tetrahydroxydiboron to H 2 .

sulfated titania nanoparticles (so42-/tio2 nps) were synthesized using titanium tetraisopropoxide (ttip) by the sol-gel method. the structure and morphology of the prepared nanocatalyst was characterized using x-ray diffraction (xrd), scanning electron microscopy (sem) and brunauer–emmett–teller (bet) methods as well as fourier transform infrared (ft-ir) and energy dispersive x-ray (edx) spectr...

novel nano-catalysts (nano zno and fe doped zno (fe(0.1)zn(0.99)o) synthesized by co-precipitation method in aqueous solution as new nanocatalysts and characterized by common techniques as ftir, xrd, sem and uvd. the size of particles obtained from xrd data is 27 and 16 nanometers for zno and fresno respectively. influences of doped fe on zno catalytic properties in oxidation of benzylic alcoho...
