Three-phase electrochemistry of a highly lipophilic neutral Ru-complex having tridentate bis(benzimidazolate)pyridine ligands

After a long haul, our paper describing three-phase experiments with a new hydrophobic Ru-complex redox-probe was finally published in Electrochimica Acta. This work is a collaboration between our group and Prof. Masa-Aki Haga’s at Chuo University in Tokyo. About two years ago Haga visited our institute and gave a talk, […]

Electrochemical reduction of 7,7,8,8-tetracyanoquinodimethane at the n-octyl pyrrolidone/water/electrode three-phase junction

Continuing our investigations of the behaviour of various redox probes at three-phase electrodes we have just published a paper looking at TCNQ (7,7,8,8-tetracyanoquinodimethane) in a standard droplet-based setup. The reason we choose TCNQ is that it’s a quinone related to the ones we studied in our previous publication on transfer […]

Anodic fabrication of nanostructured CuxS and CuNiSx thin films and their hydrogen evolution activities in acidic electrolytes

This is the latest paper in Vishwanath’s collaboration with his former group in India. In this study, they describe a simple route for direct fabrication of nanostructured copper sulphide and hybrid copper–nickel sulphide thin film electrocatalysts by direct anodization of reactive metal electrodes in sulphide ion containing electrolytes. This method […]

Electrochemistry of selected quinones at immiscible n-octyl-2-pyrrolidone/aqueous interface using a three-phase electrode system

Vishwanath’s research on cation transfer at a three-phase junction was just published1 in Electrochimica Acta. This paper looks at transfer of cations driven by a redox reaction in an organic droplet immobilised on the electrode surface. The droplet is small enough not to cover the whole electrode area, so a […]

Ruthenium ion containing N and S rich triazine based metallopolymer as a low overpotential acid stable electrocatalyst for hydrogen evolution

Another article by Vishwanath in his collaboration with his old Indian institute has just been published in Journal of Catalysis. In this paper they have shown a facile method for preparing thin films of Ruthenium ion containing metallopolymers chemically immobilised on the reactive electrode substrate. These electrodes exhibit a remarkable […]

Metal ions containing C3N3S3 coordination polymers chemisorbed to copper surface as acid stable hydrogen evolution electrocatalysts

Another paper from Vishwanath’s old work in India was just published in the very good Journal of Materials Chemistry A. Brilliant work! The paper concerns the creation of electrocatalysts for the hydrogen evolution reaction, something that is urgently needed if hydrogen shall be produced using sustainable amounts of energy. The […]
