In this study, a nano-Ca(OH)2/Fe3O4 catalyst was used to produce biodiesel from a 1:1 mixed jatropha-castor oil. By loading Ca(OH)2 onto Fe3O4 nanoparticles, it increased the specific surface area by almost 40%, which improved the catalytic activity as it provided a larger area for the reactants to interact. The main purpose of mixing jatropha oil with castor oil was to lower the viscosity of t...

Palladium catalysts have been widely adopted for organic synthesis and diverse industrial applications given their efficacy and safety, yet their biological in vivo use has been limited to date. Here we show that nanoencapsulated palladium is an effective means to target and treat disease through in vivo catalysis. Palladium nanoparticles (Pd-NPs) were created by screening different Pd compound...

In this work the properties of CoFe2o4@ B18N18 have been illustrated as a novel catalyst to compare with well-known catalyst “Fe3O4@Silica”.It has been shown that CoFe2o4 magnetite particle can be use as important catalyst inside the B18N18 ring. In our previous papers amazing result about the BnNn properties have been calculated, exhibited (Struct. Chem., 23, 551-580, (2012); J. Phys. Chem A, ...

Among the aromatic ketones, aceto phenone and its various substituted derivatives have been studied since early 20 century. This ketone can perform the self condensation reaction and produces trimmer having an aromat ic ring of 1,3,5-triphenyl benzene (T.P.B) with general fo rmula of C24H18. In this research, the compounds 1,3,5-triphenyl benzene and 1,3,5-tris (2-naphthyl) benzene are synthesi...

The effect of phosphate on adsorption and oxidation of catechol, 1,2-dihydroxybenzene, in a heterogeneous Fenton system was investigated. In situ attenuated total reflectance infrared spectroscopy (ATR-FTIR) was used to monitor the surface speciation at the nano-Fe3O4 catalyst surface. The presence of phosphate decreased the removal rate of catechol and the abatement of dissolved organic compou...

An efficient conversion of CO2 into valuable fuels and chemicals has been hotly pursued recently. Here, for the first time, we have explored a series of M12x12 nano-cages (M = B, Al, Be, Mg; X = N, P, O) for catalysis of CO2 to HCOOH. Two steps are identified in the hydrogenation process, namely, H2 activation to 2H*, and then 2H* transfer to CO2 forming HCOOH, where the barriers of two H* tran...

Carbon nanotubes (CNTs) have been under intense investigations during the past two decades due to their unique physical and chemical properties; however, there is still no commonly accepted growth mechanism to describe the growth behavior of CNTs. Here, we propose a nano Czochralski (CZ) model which regards the catalytic growth of a CNT as a CZ process taking place on the nano scale. The main i...

The overall objective of this grant is to develop a rational framework for the discovery of low cost, robust, and active nano-catalysts that will enable efficient hydrogen production. Our approach will be the first demonstration of integrated multiscale model, nano-catalyst synthesis, and nanoscale characterization assisted high throughput experimentation (HTE). We will initially demonstrate ou...

MCM-41@L-Arg@Pd(0) has been prepared by some consequence reactions. This nano structural material has been characterized via different technique including: XRD, TGA, BET, EDS, X-Ray maps, SEM, ICP-OES and FT-IR analysis. The synthesis of a variety of biphenyl compounds has been achieved successfully via a reaction of aryl halides with arylboronic acids in the presence of this nanostructure (MCM...

Cross-linked sulfonated polyacrylamide (Cross-PAA-SO3H) attached to nano-Fe3O4 as an efficientheterogeneous solid acid catalyst has been used for the preparation of spiro[pyrazoloquinoline-oxindoles]and spiro[chromenopyrazolo-oxindoles] through a four-component reactions of phenylhydrazineor hydrazine hydrate, isatins, ketoesters and naphthylamine or 2-naphthol under reflux co...
