Metal-air batteries and fuel cells show a great deal of promise in advancing low-cost, high-energy-density charge storage solutions for sustainable energy applications. To improve the activities and stabilities of electrocatalysts for the critical oxygen reduction and evolution reactions (ORR and OER, respectively), a greater understanding is needed of the catalyst/carbon interactions and carbon stability. Herein, we report how LaNiO3 (LNO) supported on nitrogen-doped carbon nanotubes (N-CNT) made from a high-yield synthesis lowers the overpotential for both the OER and ORR markedly to enable a low bifunctional window of 0.81 V at only a 51 mug cm-2 mass loading. Furthermore, the addition of LNO to the N-CNTs improves the galvanostatic stability for the OER by almost 2 orders of magnitude. The nanoscale geometries of the perovskites and the CNTs enhance the number of metal-support and charge transfer interactions and thus the activity. We use rotating ring disk electrodes (RRDEs) combined with Tafel slope analysis and ICP-OES to quantitatively separate current contributions from the OER, carbon oxidation, and even anodic iron leaching from carbon nanotubes.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-86-5, and how the biochemistry of the body works.Formula: C11H3FeO

Acylferrocenes 2a-c reacted with ortho-aminoarylaldehydes 1a-e via the Friedlnder condensation reaction to afford the corresponding ferrocenylquinolines 3a-o in moderate yields in the presence of sodium ethoxide (30mmol%) under mild reaction conditions. Under the same reaction conditions, 1,1-diacetylferrocene 2d and 1,1-dipropionylferrocene 2e reacted with ortho-aminoaldehydes 1a-e to afford the corresponding 1,1-bis(substituted quinolin-2-yl)ferrocene derivatives 3p-t. The structures of compounds 3a-t were determined and characterized by infrared, 1H NMR, mass spectrometry, and elemental analysis. The crystal structures of 3e and 3q were determined by X-ray crystallography.

Recent theoretical work (Applied Materials Today 15 (2019), pp. 139-144)has demonstrated that the cyclic voltammetry of particle-modified electrodes bears a significant level of complexity: Altered mass transport inside the porous layer gives rise to effects that may falsely suggest positive or negative catalysis. This communication reports experimental work that validates this theory. Using the well-studied oxidation of ferrocenemethanol at glassy carbon, we describe experiments in the presence of non-conducting electrochemically-inert microspheres that reproduce trends in the theoretical predictions and illustrate how experimental results may mislead. In addition, we present experimental data of the reduction of oxygen at glassy carbon electrodes modified with Nafion microspheres and show that, unless compared with theoretical work, an electrocatalytic activity of Nafion may falsely be inferred.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5

Treatment of ferrocenecarboxaldehyde with base at 0 deg C, lithium diisopropylamide (LDA) or n-butyllithium, followed by the addition of trimethylsilylcyanide, produced 1-(diisopropylamino)cyanomethylferrocene, FcCH(N2)(CN) (II) or 1-trimethylsiloxy-n-pentylferrocene.FcCH(nBu)OSiMe3 (IIIa).The reaction of naphthaldehyde, NpCHO, with LDA/Me3SiCN led to formation of 1-(diisopropylamino)cyanomethylnaphthalene, NpCH(CN) suggesting a general new synthesis for cyanoamines.The reaction of ferrocenecarboxaldehyde with Me3SiCN led to the expected silylether FeCH(CN)OSiMe3 (I).An alternative synthesis of ferrocenylmethylsilylethers, FeCH2OSiR3 (IV), involved the reaction of 1-ferrocenylmethanol with R3SiCl in the presence of pyridine.The basicity of the new silylethers III and IV is reported.

A generic amperometric bioassay based on the enzymatic oxidation catalysed by the stable NADH oxidase (NAox) from Thermus thermophilus has been developed for NADH measurements. The NAox uses O2 as its natural electron acceptor and produces H2O2 in a two-electron process. Electrochemical and spectrophotometric experiments showed that the NAox used in this work, presents a very good activity towards its substrate and, in contrary to previously mentioned NADH oxidases, does not require the addition of any exogenous flavin cofactor neither to promote nor to maintain its activity. In addition, the NAox used also works with artificial electron acceptors like ferrocene derivatives. O2 was successfully replaced by redox mediators such as hydroxymethyl ferrocene (FcCH2OH) for the regeneration of the active enzyme. Combining the NAox with the mediator and the horseradish peroxidase we developed an original, high sensitive “redox-flexible” NADH amperometric bioassay working in a large window of applied potentials in both oxidation and reduction modes. The biosensor has a continuous and complementary linearity range permitting to measure NADH concentrations starting from 5 ¡Á 10-6 M in reduction until 2 ¡Á 103 M in oxidation. This redox-flexibility allows choosing the applied potential in order to avoid electrochemical interferences. The association of the “redox-flexible” concept with NADH dependent enzymes opens a novel strategy for dehydrogenases based bioassays and biosensors. The great number of dehydrogenases available makes the concept applicable for numerous substrates to analyse. Moreover it allows the development of a wide range of biosensors on the basis of a generic platform. This gives several advantages over the previous manufacturing techniques and offers a general and flexible scheme for the fabrication of biosensors presenting high sensitivities, wide calibration ranges and less affected by electrochemical interferences.

A series of redox-labeled L-tyrosinamide (L-Tym) derivatives was prepared and the nature of the functional group and the chain length of the spacer were systematically varied in a step-by-step affinity optimization process of the tracer for the L-Tym aptamer. The choice of the labeling position on L-Tym proved to be crucial for the molecular recognition event, which could be monitored by cyclic voltammetry and is based on the different diffusion rates of free and bound targets in solution. From this screening approach an efficient electroactive tracer emerged. Comparable dissociation constants Kd were obtained for the unlabeled and labeled targets in direct or competitive binding assays. The enantiomeric tracer was prepared and its enantioselective recognition by the corresponding anti-D-Tym aptamer was demonstrated. The access to both enantiomeric tracer molecules opens the door for the development of one-pot determination of the enantiomeric excess when using different labels with well-separated redox potentials for each enantiomer. Trace compounds: Redox tracers have been synthesized for enantioselective electrochemical ligand binding assays by relying on the combined use of an oligonucleotide-aptamer receptor with the detection of the redox label. A rational step-by-step optimization procedure has been developed leading to a redox-labeled L-tyrosinamide derivative (see figure) conserving the high affinity towards the aptamer.

The encapsulation of redox mediators (i.e. ferrocene methanol, potassium ferricyanide) within the nanostructured network of organically modified silicate (ormosil) on a electrode surface is studied. The redox electrochemistry of modified electrodes made by sol-gel processing of 3-aminopropyltrimethoxysialne (3-APTMS) and 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane containing aqueous solution of desired redox mediators (potassium ferricyanide or ferrocene methanol) on electrode surface is reported. The synthetic protocol of ormosil film preparation on electrode surface also enables the encapsulation of titania (TiO2) and palladium when suitable precursors of the same are incorporated during sol-gel processing. The ormosil films are characterized by Atomic force spectroscopy, EDX and cyclic voltammetry. The modified electrodes of three different types (Ormosil, Ormosil-TiO2, and Ormosil-TiO 2-Pd) together with either ferrocene methanol or potassium ferricyanide are made to understand the redox behaviour of these electron transfer mediators present within nanostructured domain useful in electrochemical sensing with following major findings: (1) the redox electrochemistry of ormosil-encapsulated ferrocene methanol/potassium ferricyanide show gradual improvement in reversible electrochemical behavior in the order of Ormosil-TiO2-Pd > Ormosil-TiO2 and Ormosil; (2) the presence of TiO2-Pd in ormosil shows better catalytic activity as compared to that of made with only TiO2 toward ascorbic acid (AA) oxidation; (3) ferrocene methanol encapsulated ormosil has been found relatively more efficient mediator as compared to that of potassium ferricyanide toward AA oxidation. The findings justify the novel approach on the fabrication of porous chemically modified electrode of suitable nanogeometry for electroanalytical applications.
