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...

nanoporous graphene which is used as nanosorbent was synthesized by chemical vapor deposition method via porous zinc oxide nanocatalyst. the reaction was carried out using methane as the carbon source and hydrogen as the carrier gas in a ratio of 4:1 at the temperature ranging 900-1050°c for 2-50 min. the product was characterized by scanning electron microscopy, transmission electron microscop...

The befitting capping capabilities of AsO4(3-) provide a stable Cu2O nanocatalyst from a galvanic reaction between a Cu(II) precursor salt and As(0) nanoparticles. This stable Cu2O hydrosol appears to be a suitable catalyst for the one-electron transfer reversible redox reaction between Eosin Y and NaBH4. The progress of the reaction relates to three different kinetic stages. In the presence of...
