Abstract
A novel Al-doped PbO2 electrode with high oxygen evolution potential and electrochemical oxidation performance is prepared by electrodeposition technique. The Al-doped PbO2 electrode has significant improvements in electrochemical oxidation ability and electrode stability. From the morphological point of view, the introduction of Al3+ limits crystal particles and produces compact films. The films have better electrochemical oxidation ability and we demonstrated that by oxidizing aspirin. We found that the energy saving (using EE/O calculations) can be up to 34% after Al3+ doping. Meanwhile, Al-doped PbO2 electrode showed higher reusability and stability than undoped PbO2 electrode.
