How Can Electrical Conductivity be Measured in Catalysts?
Electrical conductivity in catalysts can be measured using various techniques, including:
Four-Point Probe Method: This technique measures the resistivity of a material by placing four collinear probes on the catalyst surface and passing a current through the outer probes while measuring the voltage drop between the inner probes. Impedance Spectroscopy: This method measures the impedance of a material over a range of frequencies to determine its electrical properties. Electrochemical Methods: Techniques such as cyclic voltammetry and electrochemical impedance spectroscopy are used to study the electrical conductivity and catalytic behavior of materials in electrochemical environments.
