Inactivation tests of Ascaris eggs (Ae) were performed using hydrogen peroxide and a Fenton type nanocatalyst supported on activated carbon (AC) (FeOx/C). Blank inactivation tests were also carried out using H2O2 and H2O2/AC as oxidation systems. The FeOx/C nanocatalyst was synthesized through a novel hybrid method developed in this work. The method is based on the incipient impregnation techni...

Magnetic Cellulose/Fe3O4/Co3O4 nanocomposite as a new catalyst was synthesized and characterized by FT-IR, XRD, TGA, SEM, TEM, ICP-AES and VSM techniques. The catalytic activity of this heterogeneous catalyst was studied through one-pot synthesis of 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives from three component reactions of aromatic aldehydes, 2-aminobenzothiazole,...

In this investigation, a facile and green sonochemical route has been developed for the synthesis of 2-Ketomethylquinolines by using 2-methylquinolines and several acyl chlorides in the presence of nanocrystalline MgAl2O4 as an efficient heterogeneous catalyst. The combination of nanocatalyst and ultrasonic process afforded corresponding ketomethyl quinolines in shorter re...

In this work, an efficient and green procedure for the synthesis of various substituted 1,5-benzodiazepine derivatives via a one-pot three-component catalytic reaction has been described. The reaction was conducted between o-phenylenediamine, dimedone and aldehyde derivatives in the presence of CuFe2O4 nanoparticles as a magnetic heterogeneous nanocatalyst under ball-milling conditions at room ...

This research describes application of a mesoporous nanostructured material based on basic ionic liquid anchored to silica, i.e. nano-2-(dimethylamino)-N-(silica-n-propyl)-N,N-dimethylethanaminium chloride {nano-[DMSPDE][Cl]}, as a highly effective and heterogeneous nanocatalyst for the production of 2-amino-4H-chromenes. The one-pot multi-component ...

In this study, the nano-SiO2/hexamethylenetetramine as a new basic heterogeneous nanocatalyst was prepared and used for the synthesis of pyranopyrazole via the four-component reaction. Various aldehydes, hydrazine hydrate, ethyl acetoacetate and malononitrile were reacted at room temperature under solvent-free and grinding conditions. The morphology and structure of nano-cat...

Magnetron sputtering is a widely used physical vapor deposition technique for deposition and formation of nanocatalyst thin films and clusters. Nevertheless, so far only few studies investigated this formation process at the fundamental level. We here review atomic scale molecular dynamics simulations aimed at elucidating the nanocatalyst growth process through magnetron sputtering. We first in...

Synthesized particles were characterized suitably and their catalytic role in rhodamine B by oxidation evaluated. The exhibits heterogeneous properties efficiency 93.6 91.3%, respectively....

alkanedisulfamic acid functionalized silica-coated magnetic nanoparticles (adsa-mnps) were used as effective, low-cost and reusable solid heterogeneous nanomagnetic catalysts for conversion of aldehydes and ketones to corresponding gem-dihydroperoxides and 1,2,4,5-tetraoxanes using aqueous hydrogen peroxide (30% w/w in h2o) at room temperature. these compounds are important key intermediates in...
