Defective Graphene

Defective graphene DG as a potential electrocatalyst via nitrogen elimination. A lot of topological flaws in the graphene provided a lot of catalytically active sites, high electronic conductivity, and potent CO2 adsorption. Due to these characteristics, the DG demonstrated significantly better electrocatalytic CO2 reduction performances than pristine graphene, nitrogen-doped graphene, and edge-rich graphene, with an excellent faradaic efficiency of 84% at 0.6 V vs. reversible hydrogen electrode and a higher current density. This research offers an approach that has promise for developing effective metal-free electrocatalysts for CO2 reduction.
