In the first, cadmium selenide nanoparticles loaded on activated carbon (CdSe-NP-AC) has been synthesized. Then, this new adsorbent successfully has been applied for the removal of fluoride from aqueous solution in batch studies, while the effect of various experimental parameters like initial pH, contact time and temperature on its removal percentage was examined by one at a time optimization ...

Polyvinylchloride (PVC) based heterogeneous cation exchange membranes were prepared by the solution casting technique. The effect of super activated carbon nanoparticles concentration as filler additive in membrane matrix on ionic transfer behaviors of the membrane was studied. SOM images showed uniform particles distribution and relatively uniform surfaces for the membranes. The membrane water...

Uniformly dispersed Pd nanoparticles on ZnO-passivated porous carbon were synthesized via an atomic layer deposition (ALD) technique, which was tested as a cathode material in a rechargeable Li-O2 battery, showing a highly active catalytic effect toward the electrochemical reactions-in particular, the oxygen evolution reaction. Transmission electron microscopy (TEM) showed discrete crystalline ...

A Pd-encapsulated graphite electrode was used as the negative electrode in Li-ion cells. Through dispersion of ultrafine nanoparticles of palladium on the surface of graphite, the interfacial properties of the carbon surface were modified. The presence of the palladium Ž . dramatically reduces the initial irreversible capacity of the graphite in propylene carbonate PC -based electrolyte. Pallad...

A palladium nanoparticle decorated carbon nanotube was designed as a label for preparation of a highly sensitive disposable immunosensor. The immunosensor was constructed by assembling the capture antibody on gold nanoparticles decorated graphene nanosheets modified screen printed carbon working electrode. With a sandwich immunoassay mode, the palladium nanoparticle decorated carbon nanotubes w...

In this work, the antimicrobial property of nanocomposite prepared by loading of silver nanoparticle onto activated carbon (AgNP-AC) was studied. The silver nanoparticles were synthesized biologically from the culture Enterobacter aerogenes and loaded onto the activated carbon. The nanoparticle and nanocomposite were characterized by UV-vis, scanning electron microscopy and X-ray diffraction st...

Doping of zinc with silver, palladium, and gold was found to increase reactivity towards carbon tetrachloride in water. Commercial zinc dust, cryochemically prepared zinc metal particles (SMAD nanoparticles), and zinc dust pressed into pellets (mechanically activated zinc) were employed. Reduction products detected were methane, ethylene, acetylene, and other hydrocarbons along with products of...

A novel, heterogeneous Pd-MCM-48 catalyst has been developed by encapsulating palladium nanoparticles into the cubic phase of mesoporous MCM-48 matrix at room temperature. The catalyst demonstrated excellent chemo- and regioselectivity for the hydrogenation of olefins at room temperature within 30-80 min. The turnover frequency for the hydrogenation is very high (4400 h(-1)). Interestingly, sel...
