“…Figure b shows the exchange current densities computed by using eq with the fitted value of k 0 . The blue and the red curves are computed by using C tot for Au (or Re) and Pt, respectively, and are in agreement with their experimental values, as shown by green dots. ,,− Here we use Pt as a reference given it is the most efficient single metal HER catalyst and chose Au and Re because these two metals have similar C tot , except that Re has Δ G H > 0 and Au has Δ G H < 0. As seen from the figure, j 0 for high catalytic metals (Δ G H ≅ 0) is less sensitive to α than j 0 for inert surfaces (|Δ G H | > 0).…”

The volcano trend has been widely utilized to forecast new optimum catalysts in computational chemistry while the Butler−Volmer relationship is the norm to explain current− potential characteristics from cyclic voltammetry in analytical chemistry. Herein, we develop an electrochemical model for hydrogen evolution reaction exchange currents that reconciles device-level chemistry, atomic-level volcano trend, and the Butler−Volmer relation. We show that the model is a function of the easy-to-compute hydrogen adsorption energy invariably obtained from first-principles atomic simulations. In addition, the model reproduces with high fidelity the experimental exchange currents for elemental metal catalysts over 15 orders of magnitude and is consistent with the recently proposed analytical model based on a data-driven approach. Our findings based on fundamental electrochemistry principles are general and can be applied to other reactions including CO 2 reduction, metal oxidation, and lithium (de)intercalation reactions.

“…However, the BPE reduction peak was not observed in our system using methanol (Fig. 3b), which may be a result of the dominating hydrogen evolution reaction (HER) 53 in the protic methanol solvent. When BPE was added to a solution of NiCl 2 ·6H 2 O in methanol, the reduction peak was enhanced during the negative scan (Fig.…”

“…A search for the term "potentiostatic polarization" yields hundreds of papers. One can often encounter phrasings such as the electrode is polarized to/at a particular potential in recent papers (a few examples selected from various fields can be found in Refs [16][17][18][19][20][21][22][23][24]). In the description of experiments performed with the control of potential, anodic/cathodic polarization is extensively mentioned as the indication of either the potential sweep direction, the potential range studied as compared to the rest potential of the electrode or the sign of the current hence produced [25,26].…”

This paper yields an overview on the evolution of the concept of polarization applied to electrochemical systems, ranging from electrodes to cells. The historical discussion starts at the early phase of the development of electrochemistry when current-controlled measurements were possible only, and when the early definitions of polarization, depolarization and depolarizer were created. A number of contemporary handbooks, recommendations and other reference resources are listed in which these concepts are represented in various ways, from conservative definitions to attempts of redefining them. The traditional definitions are confronted with the everyday use of professional language, drawing attention to the fact that the widespread application of potential-controlled electrochemical measurements led to new meanings. Some suggestions are made that open room for the application of the term of polarization in accord with the modern methodologies, without compromising the traditional introduction of the term. Polarization-related phenomena in biological membranes are not dealt with in the present work.
