We report the optimized synthesis and electrochemical characterization of a composite of few-layered nanostructured MoS2 along with an electroactive metal oxide BiVO4. In comparison to pristine BiVO4, and a composite of graphene/BiVO4, the MoS2/BiVO4 nanocomposite provides impressive values of charge storage with longer discharge times and improved cycling stability. Specific capacitance values...

A three-dimensionally ordered macroporous (3DOM) Li3V2(PO4)3/C cathode material with small-sized macropores (50-140 nm) is successfully synthesized using a colloidal crystal array. The 3DOM architecture is built up from fully densely sintered Li3V2(PO4)3/C nanocomposite ceramics particles. Such a 3DOM Li3V2(PO4)3/C micrometer sized particle combines the advantages of both Li3V2(PO4)3 nanocrysta...

S. Ponmani and C. Udayasoorian Abstract -A new class of nano scale zero valent iron (nZVI) particles supported on activated carbon (AC) were synthesized and the feasibility of using nanocomposite (AC+nZVI) for the removal of Cr(VI) in water was investigated through laboratory batch test. Nanocomposite was synthesized by impregnating carbon with ferrous sulfate followed by chemical reduction wit...

CoFe\(_{2}\)O\(_{4}\)/Fe\(_{3}\)O\(_{4}\) nanocomposite particles were synthesized by using co-precipitation combined with hydrothermal methods. The phase composition, surface morphology and magnetic properties of the nanocomposites investigated X- ray diffraction, scanning electron microscopy vibrating sample magnetometer. Findings show that samples comprise two phases, Fe\(_{3}\)O\(_{4}\) are...

Fe3O4 and Fe3O4/Ag core–shell nanocomposite powders were synthesized via the co-precipitation method. The structure, microstructure, magnetic, optical properties of studied. XRD patterns UV–Vis spectra showed that nanostructure particles successfully synthesized. AFM MFM mode micrographs confirm formation in nano-scale range. Both composite represented superparamagnetic behavior due to nanosize...

toluidine blue o (tbo) is a cationic dye which is extensively used in the industries. in the present paper a simple and efficient wet chemical method was introduced for removal of tbo from waste aqueous solution. magnetic multi-walled carbon nanotubes were synthesized using commercially available multi-wall carbon nanotubes and magnetic iron oxide nanoparticles which were examined for removal o...

In this work, the activated carbon/magnetic Fe3O4 nanocomposite was synthesized and characterized by TEM and XRD measurements. This magnetic nanocomposite was modified with cetylpyridinium chloride (CPC) and thus used as a new adsorbent for removal of azide ion from an aqueous solution. In an aqueous solution of azide ion, the adsorption capacity was evaluated using both the Langmuir and Freund...

A magnetic nanocomposite, using a Nopal cactus-derived biopolymer in combination with NH4OH-modified cobalt superparamagnetic (CoFe2O4) nanoparticles, was developed as green flocculant system for recovery of microalgae from aqueous solutions. The obtained nanomaterials were subsequently dispersed the matrix support ultrasonic waves. effects various factors on pectin extraction, fabrication nano...

Janus particles (JPs) are unique among the nano-/microobjects because they provide asymmetry and can thus impart drastically different chemical or physical properties. In this work, we have fabricated the magnetic halloysite nanotube (HNT)-based HNTs@Fe3O4 nanocomposite (NCs) and then anchored the Janus Au-Ni or isotropic Au nanoparticles (NPs) to the surface of external wall of sulfydryl modif...
