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...

this study focus on the preparation of two supports including activated carbon derived from medlar and palladium nanoparticles loaded on activated carbon (pd-np-ac). subsequently, both adsorbent modified with a novel schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. the method is based on c...

in this paper the role of super paramagnetic iron oxide nanoparticles (spi) on platinum nanoclusters on activated carbon (pt/c) for electrocatalytic oxygen reduction reaction was considered. four composites of pt/c and super paramagnetic iron oxide nanoparticles were prepared with the same total composites weight and different loading of pt/c (1.2, 0.6, 0.4 and 0.3 mg ). the composite attached ...

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The eff...

Li[Li0.2Ni0.16Mn0.56Co0.08]O2 nanoparticles were composited with carbon (Super P) in order to achieve an enhanced rate capability. A polydopamine pre-coating layer was introduced to facilitate the adhesion between Super P and pristine nanoparticles. The Super P particles were dispersed on the surface of Li[Li0.2Ni0.16Mn0.56Co0.08]O2 powders. The composite samples that were heat-treated in a N2 ...
