Abstract:
Scanning electrochemical probe techniques have been developed in the last 30 years for measuring spatially localized electrochemistry at micro and nano scale. Here, we will present a recently developed tool, namely Scanning Gel Electrochemical Microscopy, for imaging the electrochemical reactivity of surfaces and patterning surfaces by local electrodeposition. The concept is based on a gel probe that is in soft contact with the sample, allowing electrochemical measurements to be spatially localized in the contact area with gel as electrolyte.1 The physical resolution, or the pixel size, can th

The mean size of the Pt particles was found to be 10.7 nm. The general aspects of the electrochemical behavior were studied by cyclic voltammetry in 1 mol L-1 HClO4 aqueous solution. The response of these electrodes in relation to the oxidation of formaldehyde and methanol in acidic media was also stu

LiFePO4/C, LiFe0.98Pd0.02PO4/C, and LiFe0.96Pd0.04PO4/C composite cathode materials were synthesized using the sol-gel method. The effect of palladium on the structure and electrochemical properties of LiFePO4/C have been investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), surface area measurement (BET), charge/discharge testing, and cyclic voltammetry (CV). The results indicate that palladium doping facilitates the formation of impurities, like Li3PO4. Also, the lattice parameters of the LiFePO4 structure decrease in size as the

CNTs– TiO 2 films with different morphology were fabricated on stainless steel substrates through chemical vapor hydrolysis deposition (CVHD) process and sol–gel process, respectively. Their morphology was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The photocatalytic properties of the films were tested in the degradation of methyl orange by UV light irradiation. The results revealed that TiO 2 nanoparticles could form a continuous layer on the surface of CNTs through CVHD process. While for sol–gel process, most TiO 2 nanoparticles were isol

Abstract:
A molecularly imprinted sol-gel is reported for selective and sensitive electrochemical determination of the drug naloxone (NLX). The sensor was developed by combining molecular imprinting and sol-gel techniques and electrochemically grafting the sol solution onto a functionalized multiwall carbon nanotube modified indium-tin oxide (ITO) electrode. The sol-gel layer was obtained from acid catalyzed hydrolysis and condensation of a solution composed of triethoxyphenylsilane (TEPS) and tetraethoxysilane (TES).
