The effects of luteolin (LU) as a new mediator on the electrooxidation reduced nicotinamide adenine dinucleotide (NADH) were investigated and developed disposable NADH sensor. Firstly, screen printed carbon electrodes (SPCE) modified with gold nanoparticles (AuNP), then, LU was deposited SPCE AuNP (SPCE/AuNP) using cyclic voltammetry. Electrochemical behavior SPCE/AuNP and, redox proses found t...

Phenolic pollutants raise health and environmental concerns due to their widespread occurrence in industrial wastewaters. Electrooxidation was studied for phenol degradation different supporting electrolytes: NaCl, Na 2 SO 4 , H . Experiments were performed at constant current density 20 mA cm ?2 Two anode materials tested ? boron-doped diamond (BDD) mixed-metal oxide (MMO). Degradation process...

In this study, carbon nanotube supported Pd catalysts (Pd/CNT) are synthesized at different weight percentages by the sodium borohydride (NaBH4) reduction method to investigate catalytic performance of glucose electrooxidation reaction. 0.5% Pd/CNT, 3% and 7% Pd/CNT characterized using X-ray diffraction (XRD), electron microscopy with energy dispersive (SEM-EDX), N2 adsorption-desorption measur...

in this work, spherical pt nanometer-scale particles supported on the poly (m-toluidine)/triton x-100 film modified carbon nanotube paste electrode (pt/pmt (tx-100)/mcntpe) was used as a potent catalyst for electrooxidation of formaldehyde (hcho) in both 0.5 m h2so4 and 0.1 m naoh solutions. the obtained results showed that utilization of tx-100 as an additive during the electropolymerization p...

In this work, spherical Pt nanometer-scale particles supported on the poly (m-toluidine)/Triton X-100 film modified carbon nanotube paste electrode (Pt/PMT (TX-100)/MCNTPE) was used as a potent catalyst for electrooxidation of formaldehyde (HCHO) in both 0.5 M H2SO4 and 0.1 M NaOH solutions.

Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...

Vertical graphene nanoflake integrated films having a high density of edge planes have been used as an electrochemical platform to systematically investigate the immobilization, electrochemical oxidation kinetics and direct quantitative determination of natural DNA. Consistently, both transmission electron microscopy and atomic force microscopy observations demonstrate the presence of a self-as...
