Spectroscopic data and density functional theory calculations reveal details of remodeling process during oxygen evolution reaction.
Hydrogen is a potential clean energy source that could replace fossil fuels in the future. However, producing it without emitting carbon dioxide requires large amounts of electricity, which makes clean hydrogen too expensive for large-scale use. Making hydrogen more efficiently requires optimizing the oxygen evolution reaction (OER) that produces hydrogen from water.
Hao et al. investigated cobalt-nickel molybdate (CoNiMoO4) nanowires to determine the transition these metals undergo during OER.
One of the most common ways to improve the efficiency of the OER is to use a pre-catalyst, a substance that is converted into a catalyst during a chemical cycle, and transition metals like molybdates are…
