“…Electrocatalytic tests were performed to exploit the recognized catalytic ability of the involved materials. PbO 2 has been used as electrocatalytic material for different oxidation processes, in particular, the oxygen evolution reaction (OER), , whereas lead metal catalyzes the hydrogen evolution reaction (HER). − Under our experimental conditions, the relationship between the catalytic currents for HER and OER reactions could be representative of the PbO/PbO 2 ratio in the sample and, in turn, representative of the age of the piece. In Figure a shows the CVs obtained for contemporary lead and a sample from the Tossal de Sant Miquel (Iberian period, 2nd–4th century B.C.…”

A methodology for dating archeological lead artifacts based on the voltammetry of microparticles is described. This methodology is based on the comparison of the height of specific voltammetric features from PbO(2) and PbO corrosion products formed under long-term alteration conditions. Calibration of the method was performed with the help of a series of well-documented lead pieces from the funds of different museums of the Comunitat Valenciana (Spain) covering from the fifth century B.C. to present day. The variation of peak currents with the time of corrosion can be fitted to the same potential rate law as that found by Reich (α = 0.070 ± 0.005), using measurements on the Meissner fraction in the superconducting state of lead. The proposed electrochemical methodology enables the dating of archeological lead artifacts with a time-dependent uncertainty estimated to be ±150 years for the most ancient samples in this study.

“…In fact, the recognized catalytic ability of PbO 2 for promoting the oxygen evolution reaction (OER) [133,134] contrasts with the moderate catalytic ability of lead metal towards the electrochemical hydrogen evolution reaction (HER) [135][136][137]. Measurements on the catalytic currents for the OER and HER processes in aqueous alkaline media can thus be correlated with the Pb/PbO 2 ratio in the sample, in turn representative of the occurrence of a more or less prolonged corrosion period.…”

“…Cu is one of the most promising substitutes, because the abundance of Cu in the Earth's crust is four orders of magnitude more than Pt [ 15 ], and Cu has a more positive standard electrode potential than hydrogen, which makes it stable in non-oxidative aqueous solutions [ 16 , 17 ]. The activity of electrocatalysts on anodes or cathodes for any electrochemical energy conversion devices is highly related to their compositions and microstructures [ [18] , [19] , [20] ], especially for HER [ 21 ]. Cu has been investigated in various compositions and microstructures as electrocatalysts for HER.…”

In this work, we report on the creation of a black copper via femtosecond laser processing and its application as a novel electrode material. We show that the black copper exhibits an excellent electrocatalytic activity for hydrogen evolution reaction (HER) in alkaline solution. The laser processing results in a unique microstructure: microparticles covered by finer nanoparticles on top. Electrochemical measurements demonstrate that the kinetics of the HER is significantly accelerated after bare copper is treated and turned black. At −0.325 V (v.s. RHE) in 1 M KOH aqueous solution, the calculated area-specific charge transfer resistance of the electrode decreases sharply from 159 Ω cm 2 for the untreated copper to 1 Ω cm 2 for the black copper. The electrochemical surface area of the black copper is measured to be only 2.4 times that of the untreated copper and therefore, the significantly enhanced electrocatalytic activity of the black copper for HER is mostly a result of its unique microstructure that favors the formation and enrichment of protons on the surface of copper. This work provides a new strategy for developing high-efficient electrodes for hydrogen generation.
