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...

TiO2–FeZn nanocatalyst combined with sonolysis were used to activate peroxymonosulfate (PMS) as a highly efficient advanced oxidation process (US/TiO2–FeZn/PMS) for the decoloration of orange II dye (OII) and real textile wastewater. The characterization as-synthesized NPs was performed by SEM, FTIR, EDX XRD analyses. Optimal experimental conditions operational parameters obtained: pH = 3, 15 m...

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...

The synthesis of pharmaceutically and biologically active 2-amino-4H-chromenes was described using TiO2/nanoclinoptilolite (TiO2/NCP) as an efficient nanocatalyst under solvent-free condition. The TiO2/NCP was fabricated through modification of NCP with HDTMA, then the surface modified NCP was impregnated with titanium tetrachloride solution. Finally, the materi...

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...

this work described a simple and efficient synthesis of dialkyl 3-(alkylamino)-1-aryl-1h-pyrazole-4,5-dicarboxylates via a three component reaction between arylhydrazine, alkylisocyanid and dialkylacetylenedicarboxylates in the presence of phenylisocyanate and α-fe2o3 nanoparticles. eco friendly, solvent-free conditions, excellent yields, and short reaction times, inexpensive and readily availa...

The excellent catalytic activity of newly magnetic nanocatalyst FeAl 2 O 4 @PTMS-sulfaguanidine-SA in a one pot multicomponent Mannich-type reaction was used to obtain 2-piperazinyl quinoxaline derivatives with highly selective anti-proliferation efficacy.
