Rich defects boosting the oxygen evolution reaction

The oxygen evolution reaction (OER) with sluggish reaction kinetics and large over-potential is the severe reaction in water splitting that seems promising for energy storage and conversion. However, it is still the bottleneck ...

A water-splitting catalyst unlike any other

Electricity can be generated by renewable sources such as sunlight and wind, then used to split water, which makes hydrogen as a fuel for emerging energy devices such as fuel cells. Because hydrogen is a clean fuel, researchers ...

Tuning the electrocatalytic performance of bifunctional catalysts

In the search for highly active and inexpensive electrocatalysts, two reactions pose a particular challenge: the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Both are important for the development ...
