A poly(3,4-ethylenedioxythiophene)-b-poly(ethylene glycol) (PEDOT-b-PEG) block copolymer doped with perchlorate on FTO shows excellent optical and interfacial performance as a counter electrode (CE), such as low charge transfer resistance and low reflectivity for polymer electrolyte-based solid-state dye-sensitized solar cells (DSCs), resulting in 8.45% energy conversion efficiency, greater tha...

Due to the increasing energy demand and public awareness of climate change environmental problems, sustainable development has become one most strategic areas research. In this work, a hybrid layered thermoelectric material is produced, which consists combination poly(3,4-ethylenedioxythiophene) (PEDOT) tin sulfide (SnS). The films are produced by electrochemical deposition SnS on surface PEDOT...

In this study, making process used substrate made from TCO-FTO polymer. The TiO 2 photoelectrode layer deposited doctor blade technique and Ruthenizer dye-se...

According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. Therefore, the development of new technological approaches for waste heat recovery is highly demanded. The field of thermo...

Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...

A novel chemically modified electrode was constructed based on multi-walled carbon nanotubes, MCM48 molecular sieve composite modified glassy carbon electrode .The modified electrode showed that it can be used for simultaneous determination of acetaminophen (ACT) and codeine (COD), simultaneously. The measurements were carried out by the application of differential pulse voltammetry (DPV), cycl...

An all-solid-state fluoride ion-selective electrode (ISE) was prepared using LaF3 single crystal with poly(3,4-ethylenedioxythiophene (PEDOT) as the solid contact layer. In contrast to polymer-based ISEs, crystalline membrane-based ISEs have not been used for device, thereby prohibiting integration of on a chip. The ISE developed in this study exhibited superior sensitivity (−56.0±0.9 mV/dec) a...

a graphene nanosheets (gns) film coated glassy carbon electrode (gce) was fabricated for sensitive determination of tyrosine (tyr). the gns-based sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. the voltammetric techniques were employed to study electro-oxidation of tyr. the results revealed that the modified electrode showed an electrocatalyt...

Poly(3,4-ethylenedioxythiophene) (PEDOT) is a well-known semiconducting polymer with favorable properties which find it often applied as the active material in biological sensors and electrochromic devices. However, PEDOT has several drawbacks can prohibit its effective or long-term use, including weak adhesion to substrates such ITO-coated glass, poorly controlled surface morphology, reduced e...

this paper describes the development, electrochemical characterization and utilization of novel modified molybdenum (vi) complex-carbon nanotube paste electrode for the electrocatalytic determination of ascorbic acid (aa). the electrochemical profile of the proposed modified electrode was analyzed by cyclic voltammetry (cv) that showed a shift of the oxidation peak potential of aa about 235 mv ...
