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...

Growing industry and its effluents create a serious environmental concern. Various industrial wastes such as toxic dyes volatile organic compounds are posing threat to clean environment because of their non-biodegradable nature high chemical stability. In recent years, the degradation drugs by photo-catalysts has gained much importance proved successful approach capture light hybrid for decompo...

Water splitting for hydrogen production under sunlight using TiO2 as photo catalyst provides a better route for solar energy and attracts the attention of many researchers. The photo catalytic activity of TiO2 under sunlight irradiation depends on the band gap energy. The transition metal doped TiO2 shows an edge over TiO2 in optical absorbance and photo catalytic activity. Thin film of Cr dope...

Environmentally friendly routes from “Power-to-X” (P2X) technologies to sustainably harvest and store renewable energy with net-zero CO2 emission are imperative. The concept of P2X relies on (photo)electrolysis earth-abundant molecules into value-added products. For practical utilization, engineering robust, active, albeit inexpensive (photo)electrocatalysts via industrially compatible is indee...
