Recent advancements in nanotechnology have proposed the Carbon nanotubes as electrode material for the Supercapacitor applications due to their unique properties. Synthesis of Carbon nanotube in Catalytic Chemical vapor deposition (CCVD) is the easiest and economic way of production in a larger scale. The synthesized MWCNTs were characterized by X – ray diffraction (XRD). The morphological char...

Carbon paste electrode was modified by disodium 2,4-diamino-7-methylbenzo[g] pteridine-5,10-dioxide to fabricate a sensor for potentiometric determination of vanadyl ion (VO2+) in aqueous medium. The new ligand was synthesized in three steps with high yield. The optimal composition of the carbon paste was made of graphite powder (64.5%), ionophore (16.6%), paraffin oil (17.8%), a...

We developed a simple hydrothermal technique for the fabrication of flexible integrated composite containing cerium vanadate (CeVO4) and multi-walled carbon nanotubes (MWCNTs). The CeVO4/MWCNTs possessed good conductivity interesting electrochemical catalytic performance when immobilized on glassy electrode (GCE). This CeVO4/MWCNTs-GCE sensor provided excellent analytical detection sulfonamide ...

Both Keggin-type phosphotungstic acid (HPW) and Pd are not prominent catalysts towards the oxygen reduction (ORR), but their composite Pd-HPW catalyst produces a significantly higher electrochemical activity for the ORR in acidic media. The novel composite catalyst was synthesized by self-assembly of HPW on multi-walled carbon nanotubes (MWCNTs) via the electrostatic attraction between negative...

Pt nanoparticles (PtNPs) were synthesized in the presence of a NH(2)-terminated fourth generation poly(amido amine) (PAMAM) dendrimer as a stabilizer at different molar ratios (M:D) of metal precursor to amine terminal group of dendrimer. Subsequently, PtNPs protected by dendrimers (DENPtNPs) were covalently immobilized on multiwalled carbon nanotubes (MWCNTs) by using a condensing agent for am...

NH3-plasma treated multi-walled carbon nanotubes (pn-MWCNTs) were prepared based on the plasma technique and developed as sensing materials for detection of quercetin and kaempferol with the differential pulse voltammetry (DPV) and amperometric measurement. Such experimental parameters as pH values, accumulation potential and accumulation time were carefully investigated. The pn-MWCNTs modified...
