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...

Easily prepared nanoZnO was found to be as an efficient catalyst in the synthesis of 1,4-DHPs via four-component reaction of 1,3-dicarbonyls, aldehydes and ammonium carbonate in water at 60 °C. The prepared nanoZnO was characterized by XRD and FT-IR analysis, while the determined specific surface area of nano catalyst by BET method was 33 m2/g.

In this work, preparation and crystallization of yttrium iron garnet Y3Fe5O12 super-paramagnetic nanoparticle by aqueous sol–gel processes and its application as an effective nano catalyst for esterification and etherification reactions in short reaction time and in high isolated yields. Then this catalist was used for the synthesis of Dihydropyrimidin derivatives is described. The catalyst was...

Fe3O4 nanoparticles were employment as an efficient and magnetically separable Nano catalyst for the synthesis of amides via one-pot Beckmann rearrangement of ketones under solvent-free conditions. Various secondary amides were synthesized by this method in moderate to good yields. The catalyst showed high thermal stability and was recovered and reused at least five times without any considerab...

An  efficient  three-component  one-pot  synthesis  of 1-amidoalkyl-2-naphthols  from  2-naphthol, aldehydes, and acetamide using nano-SnO2as catalyst is described. The reactions were carried out at 80oC under water-solvent media. The structures of the compounds were characterized by IR, 1HNMR, 13C-NMR,  and  Mass  spectra  and  by  elemental  analysis.  The  advantages  of  the  effective meth...

Two simple protocols for the synthesis of tetrahydrobenzo[a]xanthenes-11-ones using nano silica phosphoric acid are reported. Short reaction times, high yields, reusability of catalyst and easy workup are some advantages of these protocols.

In this research, two series of ultra-low cement high alumina refractory castables containing 0 and 0.4 wt.% of nano-titania were prepared using different amounts of polycarbonic acid (DOLAPIX FF 26) as a dispersant. Several characteristics including microstructure, flowability, mechanical strength, bulk density and apparent porosity of the samples were analyzed. The results showed that the opt...
