Direct determination of tellurium and its redox speciation at the low nanogram level in natural waters by catalytic cathodic stripping voltammetry

Autor: Montserrat Filella, Marc Biver, François Quentel

Publikováno v: Talanta, Vol. 144 (2015) pp. 1007-1013

Tellurium is one of the elements recently identified as technologically critical and is becoming a new emergent contaminant. No reliable method exists for its determination in environmental samples such as natural waters. This gap is filled by the me

Kinetic and thermodynamic aspects of the electrocatalysis of acid reduction in organic solvent using molecular diiron-dithiolate compounds

Autor: Frédéric Gloaguen, François Quentel

Publikováno v: Electrochimica Acta. 110:641-645

In an attempt to obtain molecular H 2 production electrocatalysts achieving balanced basicity and reduction potential, we focused on the mono-substituted diiron-dithiolate derivative [Fe 2 (μ-bdt)(CO) 5 (P(OMe) 3 )] (bdt = benzenedithiolate). The el
