Plasma-Engraved Co3 O4 Nanosheets with Oxygen Vacancies and High Surface Area for the Oxygen Evolution Reaction.
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.
Journal ArticleDOI
Filling the oxygen vacancies in Co3O4 with phosphorus: an ultra-efficient electrocatalyst for overall water splitting

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.
Journal ArticleDOI
Operando Identification of the Dynamic Behavior of Oxygen Vacancy-Rich Co3O4 for Oxygen Evolution Reaction.
Zhaohui Xiao,Yu-Cheng Huang,Chung-Li Dong,Chao Xie,Zhijuan Liu,Shiqian Du,Wei Chen,Dafeng Yan,Li Tao,Zhiwen Shu,Guanhua Zhang,Huigao Duan,Yanyong Wang,Yuqin Zou,Ru Chen,Shuangyin Wang +15 more
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.
Journal ArticleDOI
