Enhanced Electrochemical Oxygen Evolution Reaction on Hydrogen Embrittled CoSe Surface (Adv. Mater. Interfaces 3/2022)

Hydrogen-Embrittled Catalyst Surface During hydrogen evolution reaction, diffuses into the catalyst grain boundaries either in atomic or molecular form and severely affects its mechanical properties causing catastrophic brittle failures (hydrogen embrittlement). The H-embrittled surface possesses good oxygen adsorption efficiency when this highly strained electrode is employed for reaction one can anticipate an enhanced catalytic activity, as reported article number 2101209 by Pitchiah Esakki Karthik, Min Jae Ko, Sung Chul Yi, co-workers.
