TL;DR: An efficient Co3 O4 -based OER electrocatalyst is designed by a plasma-engraving strategy, which not only produced higher surface area, but also generated oxygen vacancies on Co 3 O4 surface with more Co(2+) formed to improve the electronic conductivity and create more active defects for OER.

TL;DR: In this paper, an electrocatalyst with excellent performance for both hydrogen evolution reaction and oxygen evolution reaction (OER) in water splitting was designed by filling the oxygen vacancies with heteroatoms in the VO-rich Co3O4.

TL;DR: Insight is provided into the defect mechanism in Co3O4 for OER in a dynamic way by observing the surface dynamic evolution process of defective electrocatalysts and identifying the real active sites during the electrocatalysis process.

TL;DR: In this article, a proof-of-concept study on the active site evaluation for a highly oriented pyrolytic graphite catalyst with specific pentagon carbon defective patterns (D-HOPG) is presented.
