Abstract In this work, a novel system composed of non-precious nickel-based metal oxide/reduced graphene oxide nanocomposite (Ni–PbO 2 –GN) is used for electrooxidation ethylene glycol (EG) in 1.0 M NaOH solution and compares its activity with that Ni, Ni–GN, Ni–PbO . The facile electrodeposition technique to prepare the catalysts on glassy carbon (GC) substrates. outcomes electrochemical measu...

The hydrometallurgical technology provides an efficient and sustainable green lead recovery process from acid batteries. Methanesulfonic has been widely considered as a solvent for electrolytic recovery. However, the competitive precipitation of PbO2 at anode higher overpotential OER limit efficiency. In this work, anodic oxygen evolution reaction (OER) catalyst with low Ir mass fraction 7.2% i...

Lead dioxide has been studied for over 150 years as a component of the lead-acid battery. Based on first-principles calculations, we predict that by tuning the concentration of electrons in the material, through control of the defect chemistry, PbO(2) can be rendered from black to optically transparent, thus opening up applications in the field of optoelectronics.
