Nanostructured Lead Dioxide Thin Electrode

Fabrication of cerium-doped lead dioxide anode with improved electrocatalytic activity and its application for removal of Rhodamine B

“…Besides, six peaks (Inset) corresponding to three pairs of spin-orbit doublets could be identified as the Ce 3d 5/2 (v 0 , v 1 , v 2 ) and Ce 3d 3/2 and symmetric peaks centered at 141.8 eV and 137.0 eV, corresponding to Pb 4f 5/2 and Pb 4f 7/2 , respectively. This result is in agreement with the spectral values for PbO 2 [27,28]. Compared to TiO 2 -NTs/PbO 2 , the intensity of Pb 4f spectrum on TiO 2 -NTs/ Ce-PbO 2 decreases, which is probably due to the doping of cerium reducing exposing plumbum on the surface of the anode.…”

Electrodeposited PbO2 thin film as positive electrode in PbO2/AC hybrid capacitor

“…In most cases the PbO 2 deposits were a mixture of ␣-and ␤-phases except for the low current densities, as it was detected that only the ␤-phase was present with the deposition current density of 1 mA cm −2 . All XRD patterns clearly show the characteristic reflection of ␤-PbO 2 with a tetragonal structure, in accordance with literature data [30]. Only slight difference in the ␤-PbO 2 unit cell dimension was found in the three samples.…”

Discharge performance of nanostructured PbO2 microspheres as the positive active material

“…Although nano b-PbO 2 prepared by hydrolysis of Pb(CH 3 COO) 4 [4,5] showed a high discharge capacity, the hydrolytic precursor was too expensive on an industrial scale. As an alternative, the chemical oxidation of Pb(II) precursor was used to synthesize the nanosized a-PbO 2 and b-PbO 2 , which delivered an utilization ratio higher than 45% as the positive active materials of lead acid batteries [6].…”
