Extended Investigation of Electrochemical CO2 Reduction in Ethanolamine Solutions by SECM

The electrochemical reduction of carbon dioxide is very much in the focus of interest today. Intensive research is carried out in leading laboratories trying to work out methods for making useful materials from this unwanted greenhouse gas using solar or wind power generated excess electric energy. In this work, electrochemical reduction experiments are carried out in homemade cells supplied with different metal electrodes. Electrolytes containing carbon dioxide absorbing components like monoethanolamine (MEA) or KHCO3, KOH, and K2CO3 solutions are used. Metal-containing species were noticed in the used electrolytes after being in contact with the metal working electrodes. Therefore parallel to the electrochemical measurements, the metal components in the electrolyte were checked with atomic absorption methods for getting better insight into the nature of the electrode passivation. This paper attempts to compare the behavior of different electrode materials (copper, nickel) in CO2 capturing media, and investigate of the products of the electrolysis using Scanning Electrochemical Microscopy (SECM), Atomic Absorption Spectroscopy (AAS) and gas chromatography.

Recent developments, characteristics and potential applications of screen-printed electrodes in pharmaceutical and biological analysis

Screen-printed electrodes (SPEs) have gone through significant improvements over the past few decades with respect to both their format and their printing materials. Thus, SPEs have been successfully applied for the in situ detection of a plethora of analytes in a wide range of sample matrixes due to their advantageous material properties, such as disposability, simplicity, and rapid responses. In particular, the development of electrochemical sensors based on SPEs for pharmaceutical analysis has received massive consideration since they enable the rapid screening of the pharmaceutical compounds in complex matrixes, requiring small volumes of samples and no pre-treatment steps. This review summarizes the design and the working principles of electrochemical sensors based on SPEs applied to the quantification of pharmaceutical and biological compounds.

Tailoring molecular permeability of nanochannel-micelle membranes for electrochemical analysis of antioxidants in fruit juices without sample treatment

Antioxidants are widely found or used in food, pharmaceutical, and cosmetics industries; thus, rapid and sensitive detection of antioxidants is of great interest. The present work reports a simple and fast electrochemical method for direct analysis of antioxidants in fruit juices by modulating the permeability of mesochannels on the electrode surface. This goal was achieved by growing vertical silica mesochannel array (SMA) with a channel diameter of 2-3 nm on the indium tin oxide (ITO) electrode surface using the cylindrical micelles (CMs) as the template. As-prepared electrodes, designed as CM@SMA/ITO, are only permeable to lipophilic antioxidants, e.g., retinol, with the hydrophobic hydrocarbon cores of CMs. After excluding CMs from silica mesochannels, the ITO electrode modified with bare SMA, namely SMA/ITO, possesses a high density of silanol groups on the channel wall and thus is only permeable to hydrophilic antioxidants, such as ascorbic acid (AA). Two types of sensors allowed the selective analyses of retinol and AA in buffer solutions and demonstrated a wide linear range for retinol (1-60 muM) and AA (10-2000 muM), respectively, and a low detection limit (0.65 muM for retinol and 0.52 muM for AA). Moreover, the SMA/ITO electrode can selectively determine the concentration of AA in orange juice. The CM@SMA/ITO electrode can measure the sum activity of lipophilic antioxidants, such as retinol, alpha-tocopherol, and others possibly coexisting, in carrot juice. In addition, the ultrasmall mesochannels and CMs could effectively exclude the access of large substances, rendering an excellent antifouling and anti-interference ability for direct analysis of antioxidants in fruit juices without sample pretreatment.

Triggered Metal Ion Release and Oxidation: Ferrocene as a Mechanophore in Polymers

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.

Preparation and characterization of modified electrode by self-assembling ferrocene derivative

Ferrocenylmethy 1,2-dithiolane-3-pentanoate, which can be used to modify a gold electrode surface, was prepared by a condensation reaction with hydroxymethylferrocene and 1,2-dithiolane-3-pentanoic acid (D, L-alpha-lipoic acid). The condensation product has an 1,2-dithiolane ring which adheres to gold surfaces and a ferrocenyl group which is a redox site. The ferrocene rings on the modified electrode were electroactive in both acetonitrile and aqueous media.

The alpha-alkylation of ketones with alcohols in pure water catalyzed by a water-soluble Cp?Ir complex bearing a functional ligand

A water-soluble dinuclear Cp?Ir complex bearing 4,4?,6,6?-tetrahydroxy-2,2?-bipyrimidine as a bridging ligand was found to be a highly effective catalyst for the alpha-alkylation of ketones with alcohols in pure water. In the presence of catalyst (0.5 mol%), a series of desirable products were obtained with high reaction economy under environmentally benign conditions. The importance of the hydroxy group in the ligand for catalytic hydrogen transfer was confirmed by mechanism experiments. Furthermore, the application of this catalytic system for the synthesis of a biologically active molecule donepezil in pure water has been accomplished. Notably, this research would facilitate the progress of C-C bond-forming reactions in water catalyzed by water-soluble metal-ligand bifunctional catalysts.

The determination of electrochemical reactivity and sustainability on individual hyper-stoichiometric UO2+x grains by Raman microspectroscopy and scanning electrochemical microscopy

Using scanning electrochemical microscopy and Raman microspectroscopy, we have successfully observed four distinct defect structures in hyper-stoichiometric UO2+x and demonstrated the relationships between the defect structures and their ability to sustain cathodic reduction processes. When only random point defects are present, the initially inert surface is enhanced by oxidation of the UO2+x. However, when the UO2+x is already extensively oxidized and cuboctahedral clusters are present, further oxidation reduces the surface reactivity. At intermediate levels of stoichiometry corresponding to Willis clusters the surface appears to be reversibly oxidizable.

Miniature Acoustic Resonator for Enhanced Lab-on-a-Chip Electroanalysis

In lab-on-a-chip electroanalysis, the mass transfer of electroactive species towards the electrode surface limits the detection performance due to the difficulty in applying external convection. In this study, we proposed to integrate miniature acoustic resonator, fabricated by microelectrochemical system, within on-chip electroanalytical platform to improve electrochemical process. Gold film electrochemical sensor chip and acoustic resonator were assembled face-to-face with a polydimethylsiloxane chamber in between. Cyclic voltammetric (CV) responses of ferrocenemethanol were tested under actuation of miniature acoustic resonator at various powers. Resonator’s actuation results in sigmoidal CV curves and the diffusion limited current increases with the rise of applied power on resonator. The advantages of miniature acoustic resonator, including submillimeter small size, mass fabricability, low cost, low energy consumption, as well as outstanding performance towards enhancing electrochemical process, will strongly contribute to the development of highly-sensitive compact sono-electroanalytical devices.
