Herein we report that the reaction of KMnO4 with cobalt nanoparticles coated with multiple graphene layers forms a promising catalyst toward water oxidation. The compound was characterized by scanning electron microscopy, energy-dispersive spectroscopy, high resolution transmission electron microscopy, X-ray diffraction, electronic spectroscopy, Fourier transform infrared spectroscopy, and atom...

Abstract Nickel based nano-catalysts, supported on bimetallic oxide support (i.e. Ni/Al 2 O 3 -MgO) were prepared by the co-precipitation (one step, Catalyst-A) and followed impregnation (two steps, Catalyst-B) techniques separately. The catalysts then tested for dry reforming of methane (DRM) reaction. effect catalyst synthesis technique their performance has been analysed. -MgO nano-catalyst ...

For comparative means, a current Au-TiO 2 catalyst was used or order to benchmark current standards for nano-Au catalysts. The Aurolite® catalyst is currently the only commercially produced Au-TiO 2 catalyst comprising of 1% Au (by mass) loaded on P25 type TiO 2 comprising approximately 20% rutile and 80% anatase. A second batch of catalysts was examined where the catalyst composition was simil...

various aldoximes and ketoximes synthesis of corresponding aldehydes and ketones in the presence of sio2@feso4 nano composite as recoverable nano catalyst and nh2oh·hcl. the sio2@feso4 nano composite system was carried out between 10 to 15 min in oil bath (70-80 °c) under solvent-free condition in excellent yields in addition this protocol can be used for industrial scales. this method offers s...

A nano-capsule synthesized via self-catalyzed RCMP and its use as a heterogeneous catalyst nano-reactor of to generate multi-elemental particle.

The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple on...

nickel doped tio2 nano particles (1% w/w) were prepared and immobilized on nax zeolite and after characterization by x-ray diffraction (xrd) and scanning electron microscopy (sem) used as photo catalyts for degradation of orange g. the xrd patterns show that the supported tio2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the increase of tio2 loading. sc...

Direct alcohol fuel cells (DAFCs) are a type of electrochemical energy conversion device that directly Convert the chemical energy stored in a liquid alcohol fuel, commonly methanol and ethanol, and also ethylene glycol, or npropanol, to electricity. Because of their simplicity, high energy density, instantaneous recharging, and presumably long life, DAFCs have been identified as the most promi...

Introduction Various forms of carbon nanomaterials such as fullerenes, carbon nanotubes, Nano diamonds and other carbon nanomaterial’s have been rapidly developed not only for their unusual electrical and mechanical properties, but also for their potential use in Nano fluidic device [1-9]. Since 2003 Kawase et al. [10] reported the synthesis of the first Nano rings, a family of similar material...

nano-sbcl5.sio2 and sbcl5.sio2 are bench-top catalysts which are reusable, readily available, versatile andefficient for promotion of many acid catalyzed organic reactions. these catalysts do not need specialprecautions for preparation, handling or storage, and they can be stored at an ambient temperature for monthswithout losing their catalytic activity. 4-dihydropyrimidin-2(1h)-ones(thiones) ...
