Glassy carbon electrode (GCE) was modified with metal oxides (MO = Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, and the electrocatalytic properties were studied. Successful synthesis of the metal oxide nanoparticles and the MO/Pc/MWCNT composite were confirmed using FTIR, Raman and SEM techniques. The electrodes were characterized using cyclic voltammetry (CV) ...

This paper presents a simple and inexpensive method to fabricate chemically mechanically resistant hot electron-emitting composite electrodes on reusable substrates. In this study, the electron emitting were manufactured by doping polymer, nylon 6,6, with few different brands of carbon particles (graphite, black) coating metal substrates aforementioned ink layers carbon-polymer mass fractions. ...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

Electrochemically active composite film containing multiwalled carbon nanotubes (MWCNTs) and vitamin B(12) was synthesized on glassy carbon, gold, and indium tin oxide electrodes by the potentiodynamic method. The presence of MWCNTs in the composite film (MWCNT-B(12)) modified electrode mediates vitamin B(12)'s redox reaction, whereas vitamin B(12)'s redox reaction does not occur at bare electr...

Composite electrodes are an effective and cheap way to utilize a wide range of carbon materials make electrodes. More recently, thermoplastics have been widely used as the binder composite electrodes, varying fabrication approaches, such three-dimensional (3D) printing, can highly reproducible However, there is clear need understand how electrochemical performance different allotrope varies whe...

The electrochemical behavior of the herbicide paraquat was studied for an electrode modified with a PANI/CaraiaGum composite by means of square wave voltammetry. It was obtained an analytical curve in the range of 1x10 -7 to 3x10 -4 molL -1 using the following parameters: frequency of 20 Hz, wave amplitude of 80 mV, scan increment of 5 mV, an acetate buffer (pH=10) as electrolyte solution and p...

In this paper, we have reported that paper-like graphene-Ag composite films could be prepared by a facile and novel chemical reduction method at a large scale. Using ascorbic acid as a reducing agent, graphene oxide films dipped in Ag+ aqueous solutions can be easily reduced along with the decoration of different sizes of Ag particles distributed uniformly. The results reveal that the obtained ...

Carbon nanotubes (CNTs) are being investigated as a means for large-scale inspection of composite structures. Several studies have shown that CNTs possess exceptional mechanical stiffness and strength, as well as excellent electrical conductivity and piezoresistivity. Thus, it has been proposed that CNTs could be used not only to reinforce composite structures for improved impact and delaminati...

The rapid development of numerous microscale electronic devices, such as smart dust, micro or nano bio-sensors, medical implants and so on, has induced an urgent demand for integratable micro or nano battery supplies with high energy and power densities. In this work, 3D hexagonal bottle-like Si/Ge composite nanorod (NR) array electrodes with good uniformity and mechanical stability potentially...
