“…27 Recently, it has been reported that rare earth oxides were doped into PbO 2 anodes to improve their electrocatalytic capacities. [28][29][30][31][32][33][34] However, there are few previously reported studies on the Pr 2 O 3 doped into PbO 2 anode. Furthermore, coelectrodeposition is used as the mainly doping method in previous researches.…”

A lead dioxide anode doped with the praseodymium was prepared by a simple method of cyclic voltammetry (CV). Then the major work focused on the investigation of the different electrochemical performance of praseodymium doped lead dioxide anode by CV method and coelectrodeposition (CD) method. The spectral methods and electrochemical measurements were applied to analyze the physicochemical properties of the Ti/PbO 2 -Pr 2 O 3 anodes prepared by the two methods. The XRD and XPS showed the Pr 2 O 3 was successfully doped into the PbO 2 film by CV method. Comparative studies between the two doped anodes indicated that the Ti/PbO 2 -Pr 2 O 3 (CV) anode had a larger surface, a better stability and exhibited a longer service life. The experiments of degradation methyl orange as a model dye wastewater suggested that comparing with Ti/PbO 2 -Pr 2 O 3 (CD) anode, Ti/PbO 2 -Pr 2 O 3 (CV) anode had excellent electrocatalytic performance and low energy consumption. Thus, the CV modification method should be considered as a simple and promising modification method for the rare earth elements doped on the surface of many other anodes.

“…In addition, rare earth oxides, as powerful oxidants, can easily catalyze organics compounds [23]. Recently, it has been reported that rare earth oxides were doped into PbO 2 anodes to improve their electrocatalytic capacities [24][25][26][27][28][29][30][31]. Based on these reports, we can conclude that the reasonable modification is beneficial for the electrocatalytic oxidation activity and service lifetime of PbO 2 electrode.…”

“…The literature survey showed that new additives have been incorporated in the grid alloy composition in order to improve its performance. [13][14][15][16][17][18][19][20][21][22][23] Accordingly, rare earth elements, Ag and Te, were added with the purpose of enhancing the corrosion resistance. Therefore, the battery durability at higher temperatures was improved.…”

Effect of indium alloying in various concentrations with lead on both microhardness and crystallite structure of lead-indium alloy was investigated. The corrosion behavior of leadindium alloys in 4 M H 2 SO 4 acid solution was investigated by Tafel plot and electrochemical impedance spectroscopy (EIS) methods. The results of both Tafel plot extrapolation and EIS measurements exhibited the same trend. Generally, the corrosion resistance of the alloy is more significant compared with that observed for pure lead. This study shows that the addition of 0.5 pct In to Pb decreases the corrosion. However, with a further increase of alloying In, the corrosion rate of alloy starts to increase up to 5 pct In compared with that of Pb-0.5 pct In alloy. Then the corrosion rate decreases gradually with the increase in the percentage of In up to 15 pct. The values of activation energy (E a ) supported this trend of the corrosion rate which is obtained for Pb and Pb-In alloys. X-ray diffraction data exhibited broadness of peaks, which is due to lattice distortion or grain refinement. Clearly the peaks shift to higher angles for Pb-15 pct In alloy which can be attributed to changes in lattice structure of Pb. Scanning electron microscope images confirmed that the microstructure is changed with indium alloying content. The solute content tends to refine the microstructure array.
