Facile synthetic procedure for and electrochemical properties of hexa(2-thienyl)benzenes directed toward electroactive materials [PDF]

open access: yes, 2008
In the presence of RhCl3 center dot 3H(2)O and i-Pr2NEt, the cyclotrimerization of di(2-thienyl)acetylenes proceeded smoothly to afford hexa(2-thienyl)benzenes.

Electrooxidation of Methanol, Ethanol and 1-Propanol on Pd Electrode in Alkaline Medium

open access: yesInternational Journal of Electrochemical Science, 2009
Here, the oxidation activity of ethanol and 1-propanol compared methanol on Pd electrode has been studied in alkaline medium. We have used the amount of coulombs (coulometry) and apparent activation energy (Ea) to measure the activity of alcohol ...

Formic acid oxidation over hierarchical porous carbon containing PtPd catalysts [PDF]

open access: yes, 2013
The use of high surface monolithic carbon as support for catalysts offers important advantage, such as elimination of the ohmic drop originated in the interparticle contact and improved mass transport by ad-hoc pore design.

A combined "electrochemical-frustrated Lewis pair" approach to hydrogen activation: surface catalytic effects at platinum electrodes [PDF]

open access: yes, 2014
Herein, we extend our “combined electrochemical–frustrated Lewis pair” approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical–frustrated Lewis pair (FLP) system involving the B(C6F5)3 ...

Electrochemical behaviour of gamma hydroxybutyric acid at a platinum electrode in acidic medium [PDF]

open access: yes, 2013
The electrooxidation of Gamma Hydroxybutyric Acid (GHB) on a polycrystalline platinum electrode is studied by cyclic voltammetry in acidic medium. Two oxidation peaks, A and B, are obtained in the positive scan within the potential range of the double ...

Fast synthesis of platinum nanopetals and nanospheres for highly-sensitive non-enzymatic detection of glucose and selective sensing of ions [PDF]

open access: yes, 2015
Novel methods to obtain Pt nanostructured electrodes have raised particular interest due to their high performance in electrochemistry. Several nanostructuration methods proposed in the literature use costly and bulky equipment or are time-consuming due ...

Electrooxidative Functionalizations of Dehydroabietic Acid [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1987
Abstract Dehydroabietic acid methyl ester (1) was converted into 7-acetoxydehydroabietic acid methyl ester by direct electrooxidation in acetic acid and 7-oxodehydroabietic acid methyl ester by ruthenium dioxide-mediated oxidation. Non-Kolbe type electrodecarboxylation of 1 resulted in the introduction of a double bond into the ring A of

Determination of rhodium content by the method of Stripping voltammetry in ores and technogenic raw materials [PDF]

open access: yes, 2009
The method of determination of rhodium by the method of Stripping voltammetry in ores and technogenic raw materials has been developed. Determination of rhodium (III) in solution by Stripping voltammetry method was carried out by peak of selective ...

Benchmarking Catalysts for Formic Acid/Formate Electrooxidation [PDF]

open access: yesMolecules, 2021
Energy production and consumption without the use of fossil fuels are amongst the biggest challenges currently facing humankind and the scientific community. Huge efforts have been invested in creating technologies that enable closed carbon or carbon neutral fuel cycles, limiting CO2 emissions into the atmosphere. Formic acid/formate (FA) has attracted
