Electrocatalytic Oxygen Reduction Reaction

Oxygen (O2) is the most abundant element in the Earth’s crust. The oxygen reduction reaction (ORR) is also the most important reaction in life processes such as biological respiration, and in energy converting systems such as fuel cells. ORR in aqueous solutions occurs mainly by two pathways: the direct 4-electron reduction pathway from O2 to H2O, and the 2-electron reduction pathway from O2 to...

Nickel Oxide/Carbon Nanotubes as Active Hybrid Material for Oxygen Evolution Reaction

Carbon nanotubes are of great interest due to their high surface area and rich edge sites, which are favorable for wide applications. Here, a simple and efficient routine is presented by decoration of multi-wall carbon nanotube (MWCNT) with nickel oxide (NiO) nanoparticles.The morphologies of NiO-MWCNT  were  investigated  by  using scanning  electron  microscope  (SEM)  and energydispersive X-...

Electrocatalytic Oxygen Evolution Reaction in Acidic Environments Reaction Mechanisms and Catalysts

DOI: 10.1002/aenm.201601275 order to bridge the time gap between supply and demand. Molecular fuels like hydrogen or hydrocarbons produced from renewable electricity and water or CO2, respectively, can provide such a longterm chemical energy storage solution.[1–3] Considering hydrogen, its reconversion to electrical energy can be efficiently performed in fuel cells.[4] In a transition period, h...
