The synergetic effect of alloy and morphology of nanocatalysts play critical roles towards ethanol electrooxidation. In this work, we developed a novel electrocatalyst fabricated by one-pot synthesis of hierarchical flower-like palladium (Pd)-copper (Cu) alloy nanocatalysts supported on reduced graphene oxide (Pd-Cu(F)/RGO) for direct ethanol fuel cells. The structures of the catalysts were cha...

The new magnetic amine-functionalized graphene oxide (Fe3O4-GO-NH2) nanocatalyst was prepared through the reaction of 3-aminopropyltriethoxysilane (APTES) with magnetic graphene oxide (Fe3O4-GO). It was characterized by XRD, TEM, SEM, FT-IR and EDX techniques. The intrinsic carboxylic acids on the edges of Fe3O4-GO alo...

Bioreduced anthraquinone-2,6-disulfonate (AH2DS; dihydro-anthraquinone) was reacted with a 2-line, Si-substituted ferrihydrite under anoxic conditions at neutral pH in PIPES buffer. Phosphate (P) and bicarbonate (C); common adsorptive oxyanions and media/buffer components known to effect ferrihydrite mineralization; and Fe(II)aq (as a catalytic mineralization agent) were used in comparative exp...

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...

Corrosion of low alloy carbon steel in simulated crevices and a perforated envelope containing rod, mimicking the liner-overpack system, was assessed at 90 °C anoxic water-saturated clay. limited (< 1 ?m/year). The corroded surface exposed magnetite with fringe siderite. Internal corrosion heterogeneous due to gradual filling porewater, average depth for internal rod 11.5 ?m after 76 months. Ma...

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 ...
