Modulating Surface‐Active Hydrogen for Facilitating Nitrate‐to‐Ammonia Electroreduction on Layered Double Hydroxides Nanosheets

Advanced Functional Materials, EarlyView.
The NiCuFe‐layered double hydroxides nanosheets are synthesized for facilitating nitrate‐to‐ammonia with a high ammonia yield of 1.64 mmol h−1 cm−2, Faradaic efficiency of 94.8% and stability for 15 cycles. The assembled Zn‐nitrate battery delivers a remarkable power density of 12.4 mW cm−2.

Electrochemical Oxidation of Chlorpromazine Hydrochloride

Journal of Pharmaceutical Sciences, 1964
The electrolytic oxidation of chlorpromazine hydrochloride has been studied. Controlled potential coulometry has shown the chlorpromazine undergoes a two-electron oxidation in dilute aqueous acid media. In 9 N sulfuric acid two successive one-electron oxidations, involving a stable semiquinone free radical intermediate, are identifiable ...

Electrochemical oxidation of benzyl germatranes

Journal of Organometallic Chemistry, 2008
Abstract The electrooxidation of ring-substituted bromobenzylgermatranes in CH 3 CN and DMF solutions was studied. By cyclic voltammetry supported by DFT B3LYP/6-311G calculations, donor activity of the nitrogen atom was shown to be substantially reduced because of the dative N → Ge coordination compared to Et 3 N and (HOCH 2 CH 2 ) 3 N.

Unusual electrochemical oxidation of cholesterol

Steroids, 2008
It has been found that cholesterol undergoes direct electrochemical oxidation on platinum electrode in dichloromethane. Voltammetric measurements show that the process is controlled by the rate of electron transfer and the height of the oxidation peak is linear vs. concentration of cholesterol.

Electrochemical oxidation of tannery wastewater

Journal of Chemical Technology & Biotechnology, 2001
AbstractTannery wastewater was treated by an electrochemical oxidation method using Ti/Pt, Ti/PbO2 and Ti/MnO2 anodes and a Ti cathode in a two‐electrode stirred batch reactor. The changes in colour concentration, chemical oxygen demand (COD), ammonia (NH4+), sulfide and total chromium have been determined as a function of treatment time and applied ...

Electrochemically Induced Growth of Zinc Oxide

ChemPhysChem, 2007
AbstractThe electrolytically induced precipitation of zinc oxide from zinc nitrate solution on gold surfaces in the presence of water‐soluble polymers was examined for reaction times between 0.5 and 600 seconds. Regardless of the additive, polycrystalline films of zinc oxide have formed after 30 seconds, but polymeric additives dramatically change the ...

Electrochemical Oxidation

Electrochemical oxidation (EO) is able to mineralize poly- and perfluoroalkyl substances (PFAS) through potential-driven electron transfer in concert with reactions with reactive species on the anode surface. Performance of EO treatment hinges on the properties of the anode materials, the target PFAS, and the electrolytes, as well as the water quality ...

Tyrosine confounds oxidative electrochemical detection of nitric oxide

American Journal of Physiology-Heart and Circulatory Physiology, 1998
We report evidence that a porphyrinic microsensor for detection of nitric oxide (NO) also detects biologically relevant concentrations of tyrosine (Tyr) in dog brain. Tyr is oxidized by this sensor at the same potential as NO, and the sensitivity for NO and Tyr are of the same order of magnitude.
