The phase-shift method and correlation constants for determining adsorption isotherms of hydrogen at a palladium electrode interface

Determination of the Frumkin and Temkin Adsorption Isotherms of Hydrogen at Nickel/Acidic and Alkaline Aqueous Solution Interfaces Using the Phase-Shift Method and Correlation Constants

“…These aspects are described elsewhere. 17,18,[21][22][23][24][25][26] In this work, one can also confirm that the values of g and K o for the Temkin adsorption isotherms are approximately 4.6 and 10 times greater than those for the correlated Frumkin or Langmuir adsorption isotherms, respectively. The Temkin adsorption isotherms correlating with the Frumkin or Langmuir adsorption isotherms, and vice versa, are readily determined using the correlation constants.…”

“…In our previously published papers, [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] only Eq.…”

Developments in Electrochemistry: The Phase-Shift Method and Correlation Constants for Determining the Electrochemical Adsorption Isotherms at Noble and Highly Corrosion-Resistant Metal/Solution Interfaces

“…Thus, the tedious experimental procedures presented there [e.g. 13,16,[19][20][21]27] have been used to verify or confirm the validity and correctness of the phase-shift method. This is discussed in more detail in the section on theoretical and experimental backgrounds of the phase-shift method.…”

Determination of the Frumkin and Temkin Adsorption Isotherms of Underpotentially Deposited Hydrogen at Pt Group Metal Interfaces Using the Standard Gibbs Energy of Adsorption and Correlation Constants

“…7,8,11,12) These factors (ca. 4.6 and 10) can be taken as correlation constants between the Temkin and Frumkin or Langmuir adsorption isotherms.…”

“…13) However, the lateral attractive interaction (g < 0) between the OPD H species at the Pt, Ir, and Pt-Ir alloy interfaces is significantly different from the lateral repulsive interaction (g > 0) between the OPD H species at a Pd interface even though the Pd belongs to the Pt group metals. 7,[11][12][13] This aspect is frequently overlooked and confused in the Temkin adsorption isotherm of OPD H at the Pt group metal interfaces.…”
