Flower-like nanosheets FeCo2O4 for application in supercapacitor and dye-sensitized solar cell

Two-dimensional FeCo2O4 nanosheets with oxygen vacancies enable boosted oxygen evolution

“…4, both samples display typical type-IV isotherms, which further demonstrates the presence of abundant mesoporous. 43 Specifically, the BJH pore diameters of FeCo 2 O 4 and FeCo 2 O 4 -OV are calculated to be 10.9 and 12.6 nm, respectively. The Brunauer–Emmett–Teller (BET) specific surface area of pristine FeCo 2 O 4 -OV is about 74 m 2 g −1 , which is slightly larger than that of FeCo 2 O 4 (69 m 2 g −1 ) after NaBH 4 reduction.…”
