This review paper provides researcherwith a comprehensive information about the Carbon Nano tubes and the catalyst parameters that influences theproduction and morphology of the of Carbon Nano tubes.Carbon nanotubes, referred to as CNTs, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. Since discovery of CNTs in 1991, many scienti...

Nano sulfated titania was tested as solid acid heterogeneous catalyst for the synthesis of 4-(Trifluoromethyl) coumarin and coumarin derivatives under solvent-free condition. Factorial design evidenced a positive effect of reaction temperature, amount of catalyst, and solvents.  This nano-sized sulfated titania has been prepared by a sol-gel hydrothermal process. The prepared sulfated titania s...

Flammability properties of plasma pretreated cotton fabrics subjected to flame-retardant treatment were studied. Plasma pretreatment, using an atmospheric pressure plasma jet (APPJ), was applied to cotton fabrics to enhance material properties, while retaining inherent advantages of the substrates. An organic phosphorus compound (flame-retardant agent, FR) together with a melamine resin (crossl...

in this investigation, nano silica chloride (nano sio2cl) has been found to be efficient, chemoselective and recyclable catalyst for facile and simple synthesis of germinal diacetates from aromatic and heteroaromatic aldehydes in shorter reaction durations. the products were obtained in high to excellent yields. this work consistently has the advantages of excellent yields, short reaction time,...

this research proposes an efficient and easy procedure for the preparation of amides or nitriles from aldehydes. such materials were prepared via one-pot three component condensation reaction of various aldehydes in the presence of nano-ticl4.sio2 as a catalyst under thermal conditions. all reactions proceeded in high yields and in a moderately short reaction time. meanwhile, oximes were obtain...

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...
