The hydrogen evolution reaction on lead-bismuth alloys

Open circuit stability of underpotentially deposited Pb monolayer on Cu(111)

“…The current densities measured in the ''Pb Electrocapillarity'' range are compared with existing literature data for HER. Based on the values of the exchange current density j 0 = 1.58 · 10 À4 lA cm À2 and Tafel slope of 0.13 V for pure Pb electrode in, pH 2, sulfate electrolytes [38], the HER is expected to generate current density of $2 · 10 À3 lA cm À2 at overpotential of 0.13 V. Apparently, this value is an order of magnitude lower to the measured one in our experiments. This finding identifies ORR as the main driving force for Pb UPD layer stripping at OCP.…”

The Influence of Anode Composition on Energy Consumption and Current Efficiency in Zinc Electrowinning

“…28 Finally, as the chemical and physical properties of Bi is similar to Pb, they will be separated with difficulty. [29][30][31] In the present research, effect of the main parameters on the zinc electrowinning has been studied with Taguchi method (L 25 ), signal-tonoise analysis and analysis of variance (ANOVA) that were infrequent in literature. 32 Moreover, our goal was to determine a suitable alloy for anodes, among the alloys studied, based on their performances regarding increasing the current efficiency and decreasing the power consumption.…”
