Erratum: A Method for Determining the Corrosion Rate of a Metal under a Thin Electrolyte Film [J. Electrochem. Soc., 162, C135 (2015)]

Abstract

Electrolyte film thickness, X f / µm Figure 7. Plots of corrosion rates i corr of carbon steel covered with a 2 M NaNO 3 electrolyte layer as a function of the thickness of the electrolyte film. The i corr was calculated by Eq. 13 using the charge transfer resistance, R ct , obtained from curve-fitting to TML equivalent circuit and impedance at 10 mHz, Z 10mHz .On page C139, the Conclusions section should read: An EIS measurement system has been established under a thin electrolyte film. The EIS can be successfully curve fitted by a TML equivalent circuit. The method to accurately determine the parameters in the TML equivalent circuit was proposed. This method was applied to carbon steel corrosion under ultrathin electrolyte films of 5-25 μm, and it was found that the corrosion rate shows a maximum value when the thickness is approximately 20 μm.) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

Electrochemical Behavior of Dy2O3on Molybdenum and Liquid Tin Electrodes in Molten CaCl2

“…1,2 Compared with direct mixture and thermal reduction method, electrochemical technology is a better way to prepare dysprosium and alloys because of its advantages such as high processing rate and large electrochemical window. 3,4 In terms of the fundamental research on dysprosium extraction via electrochemical technology, Liu et al, 5 Shi et al 6 and Yang et al 7 studied the electrochemical behavior of Dy(III) in NaF-CaF 2 -DyF 3 , LiF-CaF 2 -DyF 3 and LiF-DyF 3 melts on a solid electrode, respectively. The deposition process of dysprosium ion in molten fluoride is a one-step reaction with the exchange of three electrons, Dy(III) + 3e − = Dy.…”

Metal–Organic Framework-Derived Mn/Ni Dual-Metal Single-Atom Catalyst for Efficient Oxygen Reduction Reaction

“…The twoelectron reduction of the hydrogen peroxide intermediate of the ORR could trigger the Fenton reaction at Fe active sites, generating strong-oxidizing radicals, which damage the material's structure and deteriorate the overall performance [36]. Different from the Fe-N-C catalyst, the Mn-N-C counterpart exhibits low reactivity for the Fenton reaction and is hardly affected by hydrogen peroxide [37][38][39][40]. Meanwhile, previously reported thermodynamic and kinetic theoretical calculation results [37][38][39][40] have also shown that Mn-N-C catalysts have a comparable catalytic performance to that of Fe-N-C. On the other hand, Ni-N-C coordination sites have been proven to exhibit excellent ORR activity and stability [41].…”

On the other hand, Ni-N-C coordination sites have been proven to exhibit excellent ORR activity and stability [41]. Recently, dual-metal single-atom catalysts (DMSACs) were designed to optimize and improve the catalytic performance of the ORR because of the unique advantage of SACs and the synergistic interaction between two adjacent metal atoms [42][43][44][45][46].…”
