Bias distribution and regulation in photoelectrochemical overall water-splitting cells
Phys.org -

The photoelectrochemical (PEC) overall water-splitting reaction (OWS) has been fully developed in the past decade, especially in new catalysts, characterization methods and reaction mechanisms. Compared with the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER) is deemed the bottleneck of OWS due to its sluggish kinetics.
