DFT-metadynamics insights on the origin of the oxygen evolution kinetics at the (100)-WSe2 surface

Water oxidation or oxygen evolution reaction (OER) in electrochemical cells is considered to be a major bottleneck in the way of hydrogen production by electro-synthesis, mainly due to a sluggish kinetics that characterizes the OER steps. Layered transitio ...
