Description

+
+

A vocabulary for all areas of catalysis initiated in NFDI4Cat. Starting with photocatalysis we add more and more terms from other areas of catalysis and related disciplines like chemical engineering or materials science.

Description

+
+

A vocabulary for all areas of catalysis initiated in NFDI4Cat. Starting with photocatalysis we add more and more terms from other areas of catalysis and related disciplines like chemical enineering or material science.

URIhttps://w3id.org/nfdi4cat/voc4cat_0007237
Definition +

An electrochemical measuring technique used for electrochemical analysis, for the determination of the kinetics and mechanism of electrode reactions, and for corrosion studies. "Voltammetry" is a family of techniques with the common characteristics that the potential of the working electrode is controlled (typically with a potentiostat) and the current flowing through the electrode is measured.
